The Input

Input starts with an integer T, denoting the number of test cases. Each test case will contain two integers a and b.

The Output

For each test case, output one line in the format "Case x: c" (quotes for clarity), where x is the case number and c is the sum of a and b.

Sample Input

2

5 10

9 4

Sample Output

Case 1: 15

Case 2: 13

C Code

#include <stdio.h>

int main(){
    int cas,i,a,b,c;
    scanf("%d",&cas);
    for(i=1;i<=cas;i++){
        scanf("%d %d",&a,&b);
        c=a+b;
        printf("Case %d: %d\n",i,c);
    }
    return 0;
}

C++ Code

#include <iostream>

using namespace std;

int main(){
    int cas,i,a,b,c;
    cin>>cas;
    for(i=1;i<=cas;i++){
        cin>>a>>b;
        c=a+b;
        cout<<"Case "<<i<<": "<<c<<endl;
    }
    return 0;
