#include <stdio.h>

int main() {
   const char *input = "42 Alice";
   int number;
   char name[20];

   int result = sscanf(input, "%d %s", &number, name);
   printf("Parsed number: %d\n", number);
   printf("Parsed name: %s\n", name);
   printf("Number of items matched: %d\n", result);
   return 0;
}

Parsed number: 42
Parsed name: Alice
Number of items matched: 2
