If you don't believe me, then what can I say except for you to read your textbook about pointers. One of our members WaltP has a very good signature
or something like that.

It's actually Salem:

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.

It's because you can't create a buffer using a variable as the size:

int buffer = 11;
	char name[buffer];

You need something like:

#include <string.h>
#include <stdio.h>
#include "input.c"

#define BUFFERSIZE  11

FILE *playerdata;

int main(void)
{
	char name[BUFFERSIZE];
	printf("Please Enter Your Name\n");
	printf("Maximum Length 10 characters\n");

And what if her name is Elizabethany? :)

abhikkumarbasu, it would really help if you'd read the threads you are responding in. He very definitely said he's using DevC++.

And I've seen other posts that you've offered the exact same advice as the post immediately before you -- and hours earlier.

We appreciate you desire to help and fully welcome it. Just try to be a little more observant so you can help people with the best advice.

add getch()

AD?!?! Really? Don't you mean getchar() ? :icon_wink:

There is so much wrong here!!!

Both of you, please read this about gets().

This loop (reformatted for readability):

#
for (n = 0;  n < 11; n++)
{
    if (strncmp(one[n],"xxxx xxxx",10) != 0 && 
        strncmp(two[n],"x,xx xxx.",10) != 0)
    {
            cout<<"Mismatch";
    }
}

has the following problems:

1) the variables only contain 10 character locations and the loop goes through 11. The last value is therefore outside the array boundries. Only go to n < 10 2) one[n] is a character, not a pointer to a character array. strncmp() only works on pointers to array.

3) Even if the compare worked, the second time through the loop you'd start at one[1] and compare 10 characters. The last character compared is again beyond the bounds of the array. Next loop is one[2] so 2 characters are beyond the array. And so on.

Another couple more things you should probably read are the Rules and this post titled Read Me: Read This Before Posting

Guys, guys, we're supposed to be 'experts' here! :D

#1: You are using a for loop but your exit criteria of the loop depends on counter and limit. Your instructions say "when the user enters a negative number or zero" and counter has no bearing on the exit.

#2: After you input your value, whether positive or negative, you process the value.

Recommendation:
#1: Try a different type of loop. There is a better choice, although for will work, it's just a little clumsy.
#2: Is there a better place to input the value within the loop so it doesn't get processed?

I have my code written very nice on my compiler with proper spacing and good alignment, how do i put it on daniweb so it looks like my compiler. everytime i make a thread and space it right the preview of the post looks messed up....

1) You could read The Rules as requested when you registered.
2) You could read the post titled "Read This Before Posting" at the top of the forum
3) You could read the words on the background of the box you typed all your messages in.
:icon_rolleyes:

Check out this link on how to do it (I'm linking rather than showing you myself because I myself haven't figured out how to make it display the words "code=C++" and "/code" as text without it getting interpreted as code).

You mean like enter code? :icon_wink:

to WaltP:
Sarcasim is Anger's Ugly cousin WaltP ;)

Oh, give me a break! :icon_rolleyes: Sarcasm is/can be a humorous way to get a point across when someone isn't listening. You would have laughed it this wasn't your post! :icon_wink:

I understand though, I will post the code I have soon as I get home. I am also sure I read over the break after each case implementation, I will go back to that part of my book.

Good, because it's in there

To your last statement, I have read the rules and the read me, I do not believe I am in violation of anything as I did not find a post anywhere on this,...

True, there are no violations. But you want help on your code. From the Read Me thread:

Keep the code short and sweet!

As much as we don't care, people insist on posting pages and pages of irrelevant code. Keep the code as short as possible. If the code isn't short, make it short by cutting out as much irrelevant code as possible. Ideally, we expect you to write a small test program that exhibits the problem you're having.

Granted, Narue didn't explicitly say "post your code", but isn't the implication quite strong? If we can't see your code, we can't tell you what's wrong with it.

Yes, computers are stupid, as MidiMagic proves. He's completely right, but the computers don't know that, so they turn the fan on when they shouldn't. We need to teach the computers that they should not generate additional heat when they are actually working rather than sitting idle. They need to follow MidiMagic's rules. He's obviously studied the phenomena.

I'll call Intel later today.

Well then, either post more professionally.. or keep to yourself in the geek's lounge.

Is this a case of the pot calling the kettle black? You seem to be acting quite below the professional level yourself, bucko. Don't give advice you aren't going to follow yourself.

The way you're reacting to it right now seems to indicate that you're more of a "baby" than the members who are giving you the negative rep.

Do some research before airing an incorrect analysis.

In any case, what you don't seem to realize is that firstly, rep is not meant to be taken seriously. It's designed to encourage members to help other people; it's not necessarily an accurate gauge of how helpful someone has been in the community.

And new members don't know this. I would have the same concern.

The second thing that you need to realize is that rep is very subjective. People give negative reputation when they deem a post "bad";

Again, research it. See my post above and tell me if bad rep was subjectively given.

Perhaps there is a reason that people are giving you bad rep? Have you ever thought of that? I mean, if people were giving you bad rep on the other site.. and people are now giving you bad rep here... it's only logical to assume that you are doing something wrong.

Yes he has. He feels they are playing childish games. And with the rep comments I've seen, he's right.

First of all, I guarantee that Dani will not disable the rep system just because you are complaining. Secondly, the rep system is not meant to be taken this seriously..

You are in no place to guarantee anything Dani might do. And the rep system is not meant to be abused, either.

And finally, all the bad rep you got was deserved.

Really? Does "Try praying, god might have pity on you and make the neg reps disappear." and "What's this? Ohh.. Ohh.. into negative rep you go!" for

Welcome to the site :)

is deserved? And since the second quote is yours, I want to know why that message deserved the rep you gave it? What a hypocrite you are!

And for another post letting members know of something they might find useful:
"Keeping up the pattern of red, sorry"
"dude... what's wrong with this dude?"
"Uhh.. there is free software out there that will encode DivX"
"Because I don't feel nice."

Childish bullys are picking on him, and I have lost …

// I haven't test this code, ...

Then you shouldn't be posting it. There's nothing worse that helping someone with code that doesn't work. (well, yes there is, but you get the idea :-)

Hey guys, the OP said

i can't find what i have to do so that my c program increments my counter by 1 it has to find and empty line.

The definition of a paragraph is not ambiguous. He defined it.

write a function for factorial and sum its digits and check for equality...it's simple..isn't it???

do u want a complete code??
if yes then sorry..nobody will help you here for that...

Good point.

...
this function returns sum of the factorials of all the digits of a given numbers sent in c
...
this will print all the numbers less than n which are special...

What happened to your previous post? Did you forget?

And stop making multiple threads on the same stupid with the same stupid title. Please read the RULES.

I tried the following way and it doesnt work:

if (cbuff[0] == '#' && cbuff[2] == 'N' && cbuff[3] == 'a' && cbuff[4] == 'm' && cbuff[5] == 'e')

Instead, how about

if (strncmp(cbuff, "# Name", 6)

Next:

strncpy (name, cbuff+8, 6);
name[6] = '\0';
strcpy(filename, name);
strcat(filename,"_TAUTOMER_");

Simplify:

strncpy (filename, cbuff+8, 6);        // Copy the first part of the name
strcpy(&filename[6], "_TAUTOMER_");    // load constant into place

And for the rest, you're close:

fidx = strlen(filename)    // get the number of characters in filename
while(cbuff[i] !='\0')     // loop until you get to the end
{
    if (isspace(chbuff[i]))
    {
        filename[fidx++] = '_';    // load an underscore for a space
    }
    else    // the character is not a space
    {
        filename[fidx++] = chbuff[i];  // load the character
    }
    i++;           // next character
}
filename[fidx++] = '\0';     // make the filename a string
strcat(filename, ".mol2")    // finish off the filename

This might be closer

i havn't given any of the code. which code r u talking abt?

Ahh, you got the point -- maybe. But then again, maybe not.

@scru
other than maybe spelling mistakes i dont see what i did wrong. computers remove from humans the need to consult dictionaries. unfortuanately that is not true on daniweb. anyway. that is redundend at this point. i was just pointing out that one could not readily understand what he meant. jasimp misunderstood him too. and many of you would have had i not figured out what he meant.

You seem to have a "don't give a damn" attitude.
1) Use a browser that highlights spelling errors. Mine (FireFox) flagged 3 above.
2) Sentences start with capital letters (A-Z) in English.
3) Contractions have apostrophes (won't, can't, you're)
:icon_wink:

>>spamming a forum
i dont see how advertising links in your signature counts as spam. i mean it does not harm anyone. and dani can claim a percentage of the profits and so it is a boon for her as well.

How can she claim a percentage?

I respect Daniweb's image of a not-for-profit community which consists of people giving their time freely because they enjoy it, rather than posting just to earn money.

"not-for-profit?" Somehow I don't think so. Dani has made it quite clear that this is not a non-profit site. The more traffic, the more she makes.

and even when he attempts to explain his insult he fails to make anyone see how it's insulting :)

I got it, without explanation :icon_twisted:

If you want to do that, do it. Output the loop index.

I think Lerner is well aware of the problems associated with system("pause") .

Then he should know better.

I wouldn't say 'never' use it. Sometimes, it is more important for a newbie to just get their program working than having to worry about the difficulties of clearing the input streams.

I would. Aren't newbies taught cin ? If so, why teach them another command? One that's not a good command to use? I stand by my statement.

The SPACEs in the scanset seem to be the problem. Remove them and see if that works for you.

Also, check out this information on
main()
while (! feof(in))

And what is the purpose of reading the file first? Just read it once.
I would also suggest rather than using fscanf() you switch to fgets()/sscanf() combo. If an error occurs with fscanf() it's harder to recover.

Talk about thread bombing! A full 2/3 of the posts have been made by nicz888, the OP. I for one can't follow the progress here because of multiple posts of 200 line programs. I have no idea what the problem is.

2) if i take line 77-92 away.
if i enter q the program will end
if i enter s it will prompt me to enter low and upper bound
if i enter s, 1, 2, 0 and 0
it will brings me back to the original prompt i can choose s,c,f....q.
when i enter q or Q. the program did end why is that???

Probably because Q or q means quit?

C'mon, guys. Stop telling him it's impossible!

Yes its impossible for a newbe.

My point is stop telling him it's impossible. Explain what he need to know to do it so he can start looking into the functionality. He can then tell that he's not ready yet.

There are ways to say no without dashing all hope... :icon_wink:

I find it interesting that someone with 300 posts and in a discussion on a "read the rules" thread hasn't read the first paragraph of this rule:

it's late thats y u are confused, give it time it will sink in, if each new user come to the site is directed to a section that show all community with solved threads we would not ahve the repitions in the forum, just like a knowledge base, for eg u go to dell to get help on a pc u select your make and model, then you sellect what category of help u want, u gettting the pic my queen,

:icon_wink:

>is along the same line as goto and gets()
I'm not sure I like you lumping goto with gets. goto is abusable, but there's nothing wrong with it. gets is completely unsafe and impossible to fix. There's quite a difference there.

I'm using a different criteria than dangerous. All three are bad coding techniques. One is dangerous. one is haphazard, one promotes disgusting code. All to be avoided.

Peoples i have tried to make this simple progrem in C...
that will print alphabets A to Z and their equivalent ASCII code.. like this
A 65
B 66
.
.
.
Z
here is da source code...

Please use English. It's "here is the source code. Unless your name is Stepin Fetchit,. Thanks. And use CODE tags...

int main (void)
{
	char code;
	for(code = "A";code <= "Z"; code += 1)
	printf("%c, %d", code[B],[/B] code);
	getch();         //  ^
}

while(fin)
  {
    ch=fin.get();
    fout.put(ch);
    
    while(ch==' ')
       ch=fin.get(); //*****

  }

If the last character in the file is a space, your inner loop will run forever because ch is never changed but the fin.get() has returned an error which you never test for.

Go back to your other code with count . It should work. This code will skip each character that follows a space. And make sure you always test for an error from all of your your inputs.

It doesn't. See http://c-faq.com/expr/evalorder2.html

And would it kill you to use some indentation (or indeed any white space).

Exactly. Study this.

Your problem is using the wrong way to test for the end of a file:

while ( !myfile.eof() )

See this ( feof() is the same as using .eof() )

I just did a quick check and found the following :icon_twisted:

Just find it interesting.... :icon_wink:

That being said, Intel is quite liberal with their documentation so there is no reason M$ couldn't have an equal or better compiler.

There's a good reason. They're M$. This generation's IBM. If they could program like they market, you'd be right. But all they really have going for them is great marketing and a stranglehold on the industry.

Actually, you don't need to understand allocation at all. The instructions say:

The file contains 10 columns and many lines.
...
It is assumed that number of students is no more than 100

So all you need is an array of 100 lines of 10 columns.

If you know structures, you can create a structure that contains
-- Student's Name
-- Array of 9 scores
Then make an array of 100 of the structures.

If not, make 1 array of 100 character strings of a maximum size for the names. Something like char names[100][21]; for 100 students with a maximum of 20 characters per name.
Then make another array for the scores, like int scores[100][9]; Since you know the exact format of each line, in a while loop, use fgets() to read an entire line. Then use sscanf() to break the line into the structure or the arrays.

The problem is unlikely to be with their code but rather ... you're using the outdated version of turbo c, which is probably very likely :)

So you claim that the outdated versions of C/C++, like Turbo, never handled strings correctly? :icon_rolleyes: Or is it that after new versions came out, the older versions simply wore out and developed bugs?

If you're going to continue to slam older compilers, at least use reasons that make sense...

So Clinton, what was the purpose of your post? How does it help sneha_venky with figuring out a project to program?

105(decimal) = 01101001(binary)

for example, i want to skip first 3 bits of binary and get the number to the right and assign it to an integer:

01001(binary) = 9 (decimal)

could you plz give a little code sample?

thanx.

Set a mask to clear the first 3 bits:

int mask = 0x1F;    // binary 00011111
newint = oldint & mask;

Pointer strings always end with a '\0' character so calling strlen to find the end just slows the whole function down. This is a good pattern to get in the habit of using.

for ( i = 0; s[i] != '\0'; ++i ) {
  /* Do stuff with the character */
}

So what if strlen() adds a few microseconds. That is not a good reason not to use it. Both versions of the loop work as expected so use the one you like best and is easiest for you to understand.

islower exists because this code doesn't always work. Some character sets have holes in the alphabet characters that aren't a part of the alphabet. Your code gives a false positive on those characters and islower wouldn't.

Yes they exist. But the technique used by VatooVatoo works just fine for all the character sets in common use, which is ASCII. Yes, EBCDIC still exists, but it is not in common use outside of IBM mainframes -- generally not a computer people learn on.

This is even worse with the holey character sets because subtracting 32 would give you a completely different character that might or might not even be a letter. That's why toupper exists.

Again, only EBCDIC would be a problem. Therefore, all three of these suggestions are good techniques to know, but not because they are bad. They are just alternatives.

The worst part is that your function doesn't append '\0' to the destination string so it's …

I am working off the code that the professor provided, but for some reason I cannot get it to work. It is giving me errors.

Duh, you think something's wrong? What's your first clue?
And how do you debug something that doesn't even compile? :icon_rolleyes:

He didn't rep me at all!! Let's ban him!

Only Ancient Dragon has the correct answer. You cannot ++ or -- the same variable in the same statement. The C Standard says doing so is undefined and not guaranteed to give the answer you expect. See this and this.

There is no need to read up on printf. The <iomanip> library provides exact functionality as printf.

Boy is that a debatable statement! :icon_wink:

You walk down the hall and when you get to the glass case, you turn towards it and fine tune your position to stand in front of the basketball trophy.

I didn't care for Rice's romanticized version of the vampire. I didn't even bother finishing Interview With A Vampire, it just didn't appeal to me. I think Salem's Lot was the best vampire book I've read.

Ineresting. I just watched the Smallville episode in which Lana became a vampire....

Did the OP really need 4 posts that say exactly the same thing? C'mon, people, one post is enough.

What this does highlight, of course, is the importance of supplying as much relevant detail as possible when asking a support question if we are going to stand any chance of answering it quickly and correctly.

And also how responses by someone that can't help the poster just makes the thread long and useless. If you're not an admin, you obviously can't help the situation with or without the user name, so why bother asking. Only admins need to respond -- IMAO...

-- ducking now, so the volley goes over my head --

I don't like the explanation you've received for "undefined behavior". What this means is the C Standard has not defined the operation, and what it is supposed to do. Therefore, any given compiler can do what they want. For fflush(stdin) , the compiler designers can write the compiler to:
1) do nothing because the command is undefined
2) do the logical thing the command implies
3) do something they think it should do, which might be logical to them but not to us
4) do anything else they want the command to do, completely unrelated to logic.

WaltP - then do something about it.

Like issue an infraction for everything you dislike? Sorry. You walked away from being moderator. Maybe you should have stayed on the mod team to deal with these young-un's in your way. It doesn't happen to be mine.

You're a moderator, issue me an infraction. I'd welcome any sign that this site hasn't spun out of control, even if the action is directed against me. Name names, take action, do something about the situation. The moderators should stop sitting on their hands.

I refuse to be a tgeer with a different name. I'm also not an SOS nor a Dragon, either. They'll do things their way. I'll point out hypocrisy, which is IMO not an infractible offence. It's just sad.

Sorry, no infractions from me. You may point out our failings all you want. Just keep it clean. And no trolling. :icon_wink:

Low bridge, everybody down!!!

naw, yall missed the profanity post that he directed at narue.. I quoted it, and responded.. but it was deleted by a mod..

Well,
1) if Narue hadn't accused him of lying (which most people would take offense at)
2) then accuse him of "selective reading", implying stupidity
3) and everyone telling him he should be able to find the course description when it's possible it may not be on the website he was looking at.

Although the responses may have been directed toward him for a reason, IMAO most were unnecessarily harsh and not conducive to having a member return. With the attitude thrown at him, it's no wonder he objected.

It's been nice knowing you, Kenya19. See you elsewhere.

A lady brought a pigeon to the vet and laid it on the examining table.

"Please do something for Cuddles! He's sick"

The Vet looks at the bird and tells her "Sorry, the bird's dead"

"No!! He can't be! Do something!"

Taken aback, the vet tries birdie CPR and artificial respiration. Nothing. "Sorry, Ma'am, he's a gonner."

"You DO something! Fix Cuddles"

"Ok", sighs the doc. He goes into the back room and brings out a huge Black Labrador. The Labrador puts his front paws on the examining table and sniffs the bird up and down. After a couple minutes, the dog turns and leaves.

"See? Nothing."

Not quite believing, She sobs, "you gotta do something. This is my Cuddles."

Resignedly, he goes into the back room again and returns with a huge Calico Tabby. The cat circles the bird a few time, sniffs a couple times, circles again. Bat's at the bird with her paws, looks up at the doc, and jumps off the table and disappears into the back room.

"See? Nothing. You have a deceased bird."

Finally believing, she says "OK. I guess Cuddles is really gone. How much do I owe you?"

"$150.00" says the vet.

"$150.00!!! Are you kidding? Just to tell me Cuddles is dead?"

"Well, it would have only been $25.00, but after the Lab test and the Cat scan..."

anyways!
I really like daniweb.

Me too...

I really like taco bell, getting ready to eat it now.

Ewwww!!!!

I love my bf.

Hope so!

I LOVE HALO.

I used to have one. Traded them in for a couple of horns. Nice red ones.

And I definitely like this thread.
It rocks. ;o)

It's OK. A little kumquatty if you ask me...

But I love taco bell. I ate it today.

Gross! Try something with a little flavor -- like Taco Johns. They Taco Bravo is great!!!

I love high school. I don't really feel like leaving.

Well, stop getting good grades and you can stay. No wait, this is America. They'll pass you anyway.
