Following program converts interger 42 to string 42 using sprintf. sprintf() writes to the character string.
$ vim integer_to_string.c[bash] #include <stdio.h> #include <string.h> int main(int argc, char **argv) { char buffer[256]; int i = 42; sprintf(buffer, "%d", i); printf("buffer = %s\n", buffer); return 0; } [/bash]
$ gcc -o integer_to_string integer_to_string.c
$ ./integer_to_string buffer = 42
