I would like to convert an integer to a string like:

int a = 12345

coverts to

char b[6] = "12345"

basically the opposite of the atoi function that converts a string to an integer.

Answer

#include <stdio.h>
int sprintf(char *str, const char *format, ...);

Example

char str[10]; 
sprintf(str,"%d", 12345);
