Printing int without using printf()

[Yammy Hung]

How to print out an integer (int) in C language without using printf()?

Thanks in advance!

Your question stinks of cheating by asking someone else to do your
homework, but what the hell ...

A note to Yammy Hung: don't try turning this in as is. There are
valid values of ints for which it fails. Fix that first.

#include <stdio.h>

void putint(int x);

int main(void)
{
puts("[output]");
putint(13725);
putchar('\n');
putint(5500);
putchar('\n');
return 0;
}

void putint(int x)
{
if (x) {
putint(x / 10);
putchar('0' + x % 10);
}
}

[output]
13725
5500

int i = 12;
char tmp[32];
snprintf(tmp, sizeof tmp, "%d", i);
puts(tmp);
return 0;
}

#include <stdio.h>
#include <limits.h>
...
char buff[1+(CHAR_BIT*sizeof(int)+2)/3+1];
sprintf (buff, "%d", the_integer);
puts (buff);

Thanks in advance!

You're welcome.
