Input output sample - 01

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

Output Specification:
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


Pascal Code:
program sample1 (input, output);

var a,b,c,cas,i: integer;

begin
     readln(cas);
     for i:=1 to cas do begin
          readln(a,b);
          c:=a+b;
          Writeln('Case ',i,': ',c);
     end;
end.


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;
}


Java Code:
import java.util.*;

class Main{
    public static void main(String args[]){
        int cas,i,a,b,c;
        Scanner sc = new Scanner(System.in);
        cas = sc.nextInt();
        for(i=1;i<=cas;i++){
            a = sc.nextInt();
            b = sc.nextInt();
            c = a+b;
            System.out.println("Case "+i+": "+c);
        }
    }
