Same set of standard replies, then you post some actual effort.

Tell me, can you even write a program to copy a file one character at a time?

Or write a program which can say count the number of 'a' characters in a file?

Or even produce a histogram showing the distribution of letters in a file?
See, having done this, you're half-way there to fulfilling one of your program requirements.

Because the same old plz help, gimme the codez refrain isn't doing you any favours at all.

a) we're not going to give you the complete answer
b) we're not going to give you much help until YOU post some code. When you post code, we know where to start with the explanations.

Get nice and comfortable, this is a long read

Well how accurate do you want the tonnes to pounds to be?

At 3 decimal places, each 1/1000th of a tonne is about 2 pounds.

So for example, 0.318 would be 701.0628, which on the face of it seems closer. Would that be rounded to even 700 as well?

I showed you 'truncate' in the hope that you might figure out 'round' for yourself.

But first, you need to decide what to round to, based on an input of decimal tonnes. If it isn't the nearest 10lb, then perhaps maybe 20 or 50.

If someone orders a tonne of sand, they're not going to be measuring it with a spoon when it's delivered.

What do you get if you
- divide by 10
- take the integer part
- multiply by 10

> void main()
Has nobody mentioned that main returns in in your previous 60 messages?
Or did you just ignore them.

Where do you
- set frequency to zero?
- determine that the word is already in the tree, and thus increment the frequency

> else(start->item==freakword);
I'd be surprised if this even compiles.
You say you've run it, is this your actual code?

> while (x || y != 00) ;
1. Remove the ; at the end
2. This isn't basic. If you want to compare both with 0, then do
while (x != 0 || y != 0)

> z = (x,y);
Meaning what?
z = y;
is what you've written.
z is int, y is double, so that's where the first problem is.

> int (int x, int y) ;
Go back to your book and study how functions are declared.

Consider that your command line parameters are actually stored in memory in a single block of memory.

./StockOrders\0datafile\0logfile\0server\0client
 ^              ^         ^        ^       ^
[0]            [1]       [2]      [3]     [4]

Then you come along with strcat(argv[3], "_fifo") And now it looks like this

./StockOrders\0datafile\0logfile\0server_fifo
 ^              ^         ^        ^      ^
[0]            [1]       [2]      [3]    [4]

Yep, you transformed client into fifo.

The short answer is, if you want to extend an argv, then you need to copy it to somewhere which has the space to append.

Other points.
1) WAY too many functions which return results are being ignored.
2) You're using gets(), the world's most dangerous function.

> if(strstr(s, "quote") && strstr(s, "buy"))
If you have s = "hello world"; and p = strstr(s, "world" ); then n = p - s; would be 5, as in printf( "%s", &s[n] ); would print world.

Bored now....

> #define MAX_MSG = 100
A segmentation fault means you ran it, and it crashed.
Whereas the code you posted won't even compile (not with that #define).

Also, use fgets() to read a whole line for you (and fopen to open the file).

Or your other post on the same subject
http://www.daniweb.com/forums/thread153215.html

You can't declare arrays using sizes available at run-time.

Given that your function definition has a constant, how about

int board[100][100];
          if(OpenBoard(boardName, width, height, board))
          {
                
          }

//...
//function definition...

bool OpenBoard(std::string *boardFileName, int *width, int *height, int board[][100])

But since this is C++, how about std::vector< std::vector<int> > board;

> BIOS Date: August 18th 2004
Which means the board is probably older still right?

You're only going to get so far by putting racing slicks on a model T ford. Looks great, but all it does is really expose how weak the rest of the system is.

By the time you've incrementally (and sub-optimally) replaced several components in your machine, you could have bought a brand new one with all the latest (and matched to each other) components for basically the same money.

Yes your fancy RAM may make it quicker (eventually), but will you ever be able to run the RAM at it's true potential on that old machine?. If the answer is no, then you've paid for performance you're never going to use.

Run mdadm in the forground, hence sequentially.
Run your progress in the background, then kill it when you're done.

And thanks for the explanations :icon_rolleyes:

If you ignore the "progress indicator" for the moment, does this actually work ?

# mdadm --manage /dev/md0 --add /dev/sdb1
# mdadm --manage /dev/md1 --add /dev/sdb2
# mdadm --manage /dev/md2 --add /dev/sdb3
# mdadm --manage /dev/md3 --add /dev/sdb4

Does /proc/mdstat exist before the first command starts, and after the last command exits?

So it does reach the far corner then.

> fill(half, a, q1, 0, 0, xc, yc, pxc, pyc, ++num);
My guess is each of these should be num+1, not num++ (or even ++num)

But then again, I can't see why it would need to be a reference either.

Don't forget, main returns int

> Anything bigger and it doesn't fill it in completely.
As in it crashes with some error message, or some other reason?

Why do you have a 'static' in fill()?
There's only ONE variable, not a separate copy for each recursive invocation.

> numbers = numbers[i+1];
When you're removing, this loop should start at the number you enter, not 0

Well as a guess, a name like "_mysql_get_client_info@0" suggests it is being decorated as a C++ symbol, whereas the equivalent in the library is very much a C symbol.

It seems to me you're compiling C++ and linking with a C library.

> Dump of file libmysql.lib
Is there a libmysql++.lib there as well?

If you post code, then someone will probably be able to help you.

It might, if you use strlen rather than sizeof

Oh, and there can only ever be one newline.
If there is a newline at all, it will always be at
input[strlen(input)-1]

Though you should check fgets() returned success before doing this.

> I've already got rid of the tabs with the tr command so its a lot more cleaner now,
And destroyed any sense of where all the columns are with it no doubt.

If the result is variable width fields, with variable content, which now overlap, then you're stuck.

Fred Flintstone 37 Wilma Pebbles
Barney Rubble 39 Betty Bam Bam

If you'd expanded the tabs with 'expand', and not gotten rid of them with 'tr', then maybe you would have multiple spaces between columns, and some sense of still having a table.

Fred Flintstone     37  Wilma   Pebbles
Barney Rubble       39  Betty   Bam Bam

At least then various utilities can count characters to establish where the fields are.

If you've still got tabs, then extracting individual fields is dead easy.
Eg. awk -F'\t' '{ print $1,$4 }' and save the removal of them until it's absolutely necessary for display purposes say. Even then, you don't mess about with your original data to do it.

Are you meant to use %c?
Because %s will do the whole thing in one call.

Or just do a difftime() between now and next Saturday @00:14, then call Sleep() for that many seconds.

One calculation, one call to Sleep().
5 lines of code, and it's sorted.

What's your definition of "simple"?

Or put it another way, what have you been studying for the past few weeks or months, and how much attention were you paying?

Better swing by this one a few more times, until you get it
http://www.daniweb.com/forums/announcement8-3.html

http://en.wikipedia.org/wiki/Karnaugh_map

Step 1 - a loop which reads numbers and prints them out (this should be basically the same as a previous assignment)
Step 2 - make it exit on ctrl-z
Step 3 - make it reject out of range numbers
Got the idea yet?

Think about what steps you can
a) acomplish
b) might need to do first

When you've got somewhere (and got stuck), then post back.

Don't just stare at your "elephant" and complain that it's too big to eat all at once.

So if you have

while ( cin.getline(input1, 31, '\n') ) {
  cout << "--" << input1 << "--" << endl;
}
if ( cin.fail() ) {
  cout << "Failed" << endl;
}
if ( cin.eof() ) {
  cout << "EOF" << endl;
}
if ( cin.bad() ) {
  cout << "bad, very bad" << endl;
}

If you use an arrow key, what happens here?
- loops a few times, then prints one of the exit messages?
- loops a few times, printing various fragments of the edited input, then goes back to waiting.

http://www.cppreference.com/wiki/io/fail

To get out of the loop, press ctrl-d, and you should see EOF printed.

If the code keeps in the loop, but prints various fragments of the line in several attempts, you should be able to recover.

Oh, and please find a way of copying the code accurately (pen drive, email yourself, whatever). It'll save a lot of confusion in the long run.

Excellent first post - code tags, environment, statement of problem and example code. Everyone else should learn from this!

> strcyp (input1, default1);
Does this compile?
Isn't it supposed to be strcpy() ?

> the program will ignore (or seem to ignore) all of my "cin.ignore(1000, '\n');" and
> "cin.getline(input1, 31, '\n');" commands.
Or they could be returning error.
Check the return result to see if this is the case.

How much research did you do between reading my reply and posting your reply?

> will the first argument be the file name from which the program has been called?
Yes.
You can even use the registry to specify command line options if you wanted to.

> What do you mean about not standard C anymore?
Meaning you can no longer pick a random C compiler (say for your Cray supercomputer or your mobile phone), and have your program work on all of them.

> Is it about making and using custom library?
Not necessarily. It could just be using the header files which describe the API of the OS you happen to be using. The Win32 API for example has many useful things which could be used to solve this problem.

Check out the console tutorials here

In the same way you count down the dots, count up in numbers.

Without access to your platform, I've got nothing.

Apart from reading the manuals very carefully.
Focus on tcsetattr, tcgetattr and termios.

There may be some other thing you have to call, possibly right at the start of the program before you do any I/O (including printf).

Finding a forum specific to your platform may also help, if there is such a thing.

Nope - http://www.daniweb.com/forums/announcement8-2.html
You make an effort, then we help.

typedef struct{
        process *data;
        struct queue *next;
} queue;

The "struct queue" inside the typedef refers to an as yet undefined struct.

You need to name your struct, before you can point to it. Fortunately, this is easy to do, like so.

typedef struct queue_tag {
        process *data;
        struct queue_tag *next;
} queue;

Which OS / Compiler are you using?

Sure it's possible, but it won't be standard C anymore.
