convert int to char

[John Carroll]

Does anyone have a function or procedure for converting integers to
character strings?

Thank you,
John

#include <stdio.h>

int main( void ) {

int i = 1234;
char string[100];

sprintf( string, "%d", i );
puts( string );
return 0;
}

If one cared to go through the bother, one could, completely
within standard C for hosted environments, open a file read/write,
printf() to produce the character string output, rewind to the
beginning of the file, and read the string in to the desired
destination buffer. Sure it'd be clunky, but conformant.

I have actually used this trick to implement snprintf().

Remember to rewind the file twice! :-) (Once after the vfprintf,
once more after reading the printed output.)

itoa() exists, I assume it is non-standard??

I listed printf() because what do you do with a string. fprintf() would
be the other destination.

It only exists if you publish its source code. For example:

char *itoa(int i)
{
if ('i' == i) return "a";
else return "";
}

which should quite reliably convert 'i's into 'a's. Maybe you now
appreciate the point?

You can do anything you like with a string. Printing it to stdout or
to a specified file doesn't begin to exhaust the possibilities.

printf() may convert the integer to a character string internally, but
that doesn't help if you want to get at the character string (which is
what the OP was asking for).

We must do something. This is something. Therefore, we must do this.

itoa is the homework exercises from K&R, section 3.6, Loops - Do-while

If it not standard, it doesn't exist :-)

I once asked an expert COBOL programmer, how to
declare local variables in COBOL, the reply was:
"what is a local variable?"

That's one of the stupid attitudes which encourages people to label
comp.lang.c as a bunch of ego-wankers.

Of course itoa() exists on many systems and in many program sources. It
simply isn't On Topic for this newsgroup, and can't be used portably.

But can it be written portably? That's a valid question here.

Did you notice the smiley? Being humor-impaired is one of the other
things that causes the above reaction.
