//Header file: #include <stdio.h> //Declaration: int snprintf(char * restrict buf, size_t num, const char * restrict format, ...)

1. include <stdio.h>

int main () {

 char buffer [50];
 int n, a=5, b=3;
 n=snprintf (buffer, 5,"%d plus %d is %d", a, b, a+b);
 printf ("[%s] is a %d char long string\n",buffer,n);
 return 0;
