try this code.

But he wants it for the computer, not the iPhone... :D

And you don't need to call a function to exit, just return 0;

i should have posted there error messages, but there were 50 somthing...i did not see the two typo's of namespace and <string>. ty

So just post the first 5 or so. Usually the first one you fix gets rid of a lot of the errors.

Reformatting slightly, is this what you really want?

rectangleType::rectangleType(double l, double w ) :lineType(l)
{
    width=w;
}//end lineType constructor

Please forgive me...I'm still new posting anything in these forums but...code tags? I'm sorry. That probably seems stupid of me to not know what that means. Like I said, I'm new to posting in these forums and as far as programming goes, I'm still pretty new to that too. I'm only in my second computer science class right now. Thanks.

Subtract 24.

Set grade total to 0
Start a loop.
For each input, add the appropriate value to grade total
Count each input.

You can figure out how/when to end the loop and calculate the rest of the grade

i am having a few errors compiling a code in visual C++ with my jumble word code, can anyone help?

Yes we can, if you give us an idea what's wrong. We can't see your screen with the errors.

>>when I tried to run it, it suddenly closed

That's because there is nothing at the end of main() to prevent that behavior. If you want it to stay open so that you can see it, then add getche(); at the end of main(). The program will then stop until you hit a key.

Dragonmeister!?!?! getche() ?!?!? getchar() please. It's at least standard...

OK, but you need to read the Forum Rules and the Sticky Posts first.

None that I can be bothered to mention any more, thanks to your vague requirements.

Its not vague...
Can someone else please help....

If Salem can't understand what you need, believe us, your description is very vague... You can't prove it isn't by simply saying so.

So far you've refused the help. I will now be exceptionally clear and repeat: READ THIS!!!! Especially the section titles Describe your problem clearly and fully!

Did you post code? Did you explain what the problem was? Did you give us any information to help you? No. You only said "send me code" and that is asking us to write it for you.

Start month at 1 (January)
If your day > #days-in-January
Subtract #days-in-January from your day, add one to month.
If your day > #days-in-February
Subtract #days-in-February from your day, add one to month.
etc.
The first time day <= #days-in-'month', you have your answer.

Set up a loop and an array to do this.

i need help in making c++ code for tic tac toe on 7x7 board by using mini max and alpha beta where 4 in a row ,column,and diagonal are winning state , if some 1 can share code it will be quite help full 4 me

We don't write code for people. We help them fix the code they write.

i make a code that was working properly on human vs human but not on human to computer

Then you wrote it wrong.

i already make a code that was working properly on 3x3 board but not on 7x7 on 7x7 it work properly as human vs human but not on computer vs human on this it stuck up ....

And it's going to remain stuck up until you start reading the Forum Rules and the important Sticky Posts at the top of the forum.

OK! I understand that I can't read a file exactly as I think. So I'm asking again but different : How can I do this process :
the file is:
11111111110000000000
the compressed file is 10111010. <----5x1 5x0

How I can I do that ? It should be a way to do that. If it not possible on C, I know little bit Java maybe I can do it on Java ?!

Is the file a bunch of text characters 1 and 0? Or is it in fact a bunch of bytes 0xFF 0xA0 0x00?

We don't know what "the file is" really describes.

and how do you know 10111010 is 5x1 5x0 and not 0Bx1 1x0 or 2x1 3x0 1x0?

This code you are asked to input a number and it will tell u wheter or not the input you entered is in the array or not
i am having issues with this code and its giving me some errors,
if anyone wants to help me out it will be greatly appreciated!

Stop posting your questions as Code Snippets.
When you ask a question, give details! "Having issues" does not give us any information. Explain your problems and give us an idea where the problem is.

Maybe you should be clearer... :icon_wink:

Do not resurrect an old thread to ask a question. You should only post help to an existing thread.

Now go start your own thread and reword your question giving us all the detail necessary for understanding exactly what you want.

Sure. Read this.

1) Format your code so we can easily follow it
2) Never paraphrase an error -- give it to us exactly!
3) Out of 145 lines, which one has the error?
4) main() is an int function -- see this
5) Why are you using conio.h. There is nothing in that header you really need. And it's not Standard C.

Learn both. They both have their uses and one can do things better than the other in many cases. It also gives you the ability to choose the best language for the job.

And of course, the not-so-smart programmers are cheaper... :icon_wink:

et. Like in the Beverly Hillbillies -- I et possum stew.

Oh, you mean Detroit! De - twa.

this is my daughters homework she asked me to help and now im stuck she has worked it out and is making me look stupid need to get my selfrespect back even if i have to cheat(i used my brain and im asking you) the code is as follows but i cannot get it to work

IMO, you'll get more respect from her (which is more important than your own) by admitting she's better and having her teach you. It'll do wonders for her self esteem, which is sadly lacking in people now-a-days. And you'll feel better knowing you gave her a great ego boost.

By the way, no one can make you feel stupid. Only you can do that.

This is not a code snippet. This is a help question. Read the Rules before posting.

I want to read a file exactly how it is on my hdd . like this: 101010111111000101010 . I have to create a new file after reading by changing some 1 and 0s . I have to change them to compress the file.. For example (very simple example) the file is :
11111111110000000000
the compressed file is :
solving :5x1 5x0

the file is 10111010.
I have a big plan for that! But first off all I need to know how to read and write a file as binary...

WaltP you can't do that as opening the file as binary. I don't know why :(

The only way to read a file as binary is to open the file in binary mode. If it doesn't work, you can't read the file. Period.

You are under the misconception that reading in binary reads a bit at a time. Not true. It read the same as anything else -- bytes from the file are moved into bytes ( char s) into your read buffer. And that is exactly how it is on the disk -- a series of bytes.

After reading, it's then your job to look at the values as bits.

Add to that, there is no bit type in C. The lowest you can deal with is a byte.

int getAvg(school student, total)
{
    ...
}

What type of variable is student ?
What type of variable is total ?

Open the file as binary.

For UP, if number is MIN, set number to MAX.
For DOWN, if number is MAX, set number to MIN.

If you are having trouble with step 2, you should not have any code for step 3 and beyond.

Edit out all the stuff you cannot test without step 2 being finished.
Then perfect step 2.
Add step 3 and make sure it works.
Then start adding step 4, a piece at a time.

The hardest way to write any program is to write the whole thing then start testing. You get lost fast.

Then there is Detroit.

Does there have to be? I grew up there, so I'm trying to forget... :scared:

For example, your wrapper could keep track of all the memory allocated and deallocated. This would help you make sure you aren't attempting to deallocate twice, or not deallocating at all.

Tell us how you would add two matrices on paper.

So declare total . What type of variable is it?

In AddNewElmnt() you never checked the list to see if the character entered is already there. Check before adding.

Because in the first case, the pointer p is pointing nowhere. You defined the pointer, but never pointed it to space for the data.

In the second, you allocated data space, and the address was placed into the pointer. But the only reason it didn't segfault is luck. The space malloc 'd obviously included some fudge room. It could be that the malloc actually allocates a buffer in chunks by K. Another malloc would take more from that chunk without having to access the heap.

Yes. But the '\0' in 7 is the end of the string so the last few characters are essentially invisible.

and you do not want to rely on someone typing less than 12 characters.

The problem here is that although I manage to rename the file name from "unsaved.txt" to whatever the user enters, the global char* variable (fileName) won't change and remain "unsaved.txt" so the next time I try to write something new into this file it will still create a new "unsaved.txt".

You cannot change the contents of a constant string, which I assume is your problem. If you have: char *fname = "unsaved.txt"; it's a string constant and cannot be modified.

On the other hand, if you have char fname[] = "unsaved.txt"; you can change the name. But if you change it to "theRealFileName.txt" you have another problem. You just moved 20 characters into a string defined as 12 characters so you overwrote unknown memory -- a very bad thing.

To fix that, define the string as char fname[100] = "unsaved.txt"; and you'll have 99 characters to play with.

It means the people that designed the compiler assigned the value E2293 to the error. And unless you miscopied the error, it is ") expected".
So look above whatever line is wrong for a missing )

FORMAT!!!! How do you expect us to read that?!?! Use the PREVIEW button and if you don't like what you see, neither will we -- fix it!

If your pumps hold 100 gallons and you ask for more than 100 gallons, the pumps at that station can't handle the requests. Seems to me going to another station with greater pump capacity is the answer...

Unless you didn't explain your task fully.

This is NOT a code snippet, this is a help request. Post properly. Look up what a code snippet is if you are unsure.

I have connected to the IRC a few times, but no-one is ever on when I do :)

Makes sense. With the 8 or so people that use it, the chances that any one of them are on at the exact time someone enters the IRC is slim at best. And assuming someone waits around for 5 minutes hoping, there are only 287 5 minute slices in the day the others may show up -- a slim margin.

Not a clue how this can be rectified... A bulletin board where someone can post when they will be around might work -- assuming someone can plan that far ahead

Allocate a large temporary chunk of memory when recording starts. If you need more space, allocate another temporary chunk -- not one at a time -- to save time. Keep track of your chunks.
When you stop recording, Allocate one more chunk just large enough to hold the entire recording and move the recording into it, deallocate the temporary memory.

This can be more elegant, but it should get you started. Also, look into reallocate commands. They may help, too.

What am I doing wrong?

Not reading this and this as requested, and assuming we are psychic.

Yet Another Version of Findind a Prime number:

snipped

i Hope this is the Efficient Version of All.
Any other ways, Plz Welcome.

I hope this is a joke.

Please, do not take this code seriously... :icon_rolleyes:

Recommendation---

Start over.
Write the input function. Test it.
Write the display function. Test it.

you can copy the code from the current code to make it faster, but from now on *never* write the entire project without compiling and testing often. Write it in segments.

Like gauche, which is not used frequently anywhere, and literature reflects common language more than anything. I challenge you to find in any writings or documents where the word gauche is used in any way that could be described as commonly.

I must bow to your extremely well-read self. I for one don't have time to read all books, magazines and newspapers that [have been/are being] printed in the English-speaking world, so I'm sure I've missed quite a few.

Hi all,

I am stuck here after several hours tried.
Here the thing. I have txt file that contain float data (1 column and many row) such like this (4 float data):

0.799
0.851
0.926
1.000

Then i want to read it as array. My code is work until this point.
After read it as array, than the code should copy each data
as much as number enter by user.
The user should enter 4 different number, since there are 4 float data in the read txt file.
For example if user enter number 2,3,1,2 respectively, the code must copy the 0.799 two times, the 0.851 three times, and so on.
Then put in the different txt file.
In this case the contain of new txt file must:
0.799
0.799
0.851
0.851
0.851
0.926
1.000
1.000

My coding failed to do this task, instead copying each of data as accumulation number input by user. So in this case the accumulative value from 2,3,1,2 is 8 (2+3+1+2).
My result so far are:
0.799
0.799
...
0.799 (until 8 row, then)
0.851
0.851
...
0.851 (until 8 row..and so on )

My guess is you're supposed to enter as many numbers as in the file, right? So after you read the file, set up another loop and input the numbers into another array. Now your …
