Problem:
Print Test Cases

In the online judge system, a judge file may include multiple datasets to check whether the submitted program outputs a correct answer for each test case. This task is to practice solving a problem with multiple datasets.

Write a program which reads an integer x and print it as is. Note that multiple datasets are given for this problem.

Input

The input consists of multiple datasets. Each dataset consists of an integer x in a line.

The input ends with an integer 0. You program should not process (print) for this terminal symbol.

Output

For each dataset, print x in the following format:

Case i: x

where i is the case number which starts with 1. Put a single space between "Case" and i. Also, put a single space between ':' and x.

Constraints

1 ≤ x ≤ 10000

The number of datasets ≤ 10000

Sample Input

3
5
11
7
8
19
0

Sample Output

Case 1: 3
Case 2: 5
Case 3: 11
Case 4: 7
Case 5: 8
Case 6: 19

Solution in C++14 (judge verdict: Accepted)

#include<iostream>
using namespace std;

int main(){
    int x[10000];
    
    int n=0;
    while(true){
        if (n>10000) return -1;
        
        cin >> x[n];
        
        if(x[n] == 0) break;
        
        ++n;
    }
    
    for(int i=0;i<n;++i){
        cout<<"Case "<< i+1 << ": "<<x[i]<<endl;
    }
    
    return 0;
}
