[Dev-C++] itoa()

[Ioannis V. <iv...@em...>]

Ok, in order to be complete (with what I consider as an itoa() without =
any
specific constraint requirements) I repost a complete itoa(), with the =
few
bugs fixed. The implementation was influenced by the spirit "(Real
programmers) Don't comment their code. If it was hard to write, it =
should be
hard to
understand and even harder to modify." See the attached file.


#include <stddef.h>
#include <stdlib.h>
#include <stdio.h>


char *itoa(int i)
{
  size_t Length;
  char *p;
  int temp=3Di;
=20
  int sign=3Dtemp<0?-1:1;
=20
  if(!sign)
  {
    p=3Dmalloc(2);
 =09
    if(!p)
      return NULL;
 	 =20
    p[0]=3D'0', p[1]=3D0;

    return p;
   }
=20
  temp=3Dsign*i;

  for(Length=3D0; temp/=3D10; Length++)
      ;

  p=3Dmalloc(Length+1+!sign=3D=3D1);

  if(!p)
    return NULL;

   sprintf(p, "%d", i);
=20
  return p;
}
