Hi -

"Itoa" was popular in a number of DOS-era compilers (like Turbo C), but it was never officially a "Standard C" library function, and it was notoriously vulnerable to buffer overruns.

"sprintf()" is an alternative to "itoa()"; "snprintf()" is an even better alternative:

Code:

#include <stdio.h>

int
main ()
{
  char s[80];
  int iret = snprintf (s, sizeof (s), "%d", 100);
  printf ("string= %s, snprintf return value= %d...\n", s, iret);
  return 0;
}

'Hope that helps .. PSM

PS:
I assume when you say "itoa isn't working correctly", you probably mean that your compiler isn't recognizing it as a valid function. Again, "snprintf" is probably both a more portable and more robust solution...

Please help us to help you. 'not working correctly' is not enough information to diagnose your problem. Show us what you have tried, and explain in what way it is failing.
