sprintf - is identical to printf() except that the output is a char array in C

//Declaration:  int sprintf(char *buf, const char *format, ...); 
//Return:       returns the number of characters actually placed into the array. 
#include <stdio.h>

int main(void){
  char str[80];

  sprintf(str,"%s %d %c", "one", 2, '3');

  printf("%s", str);
}
