In this problem, we're asked to just add two input numbers and print them out accordingly. Here's the code.

#include <bits/stdc++.h>
using namespace std;

int main() {
  int T, i=1;
  scanf("%d", &T);
  while (T-- > 0) {
    int a, b;
    scanf("%d %d", &a, &b);
    printf("Case %d: %d\n", i++, a+b);
  }
  
  return 0;
}
