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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

#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; }
