C - A+B for Input-Output Practice (II)

Your task is to Calculate a + b.

InputInput contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line.
OutputFor each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
Sample Input

2
1 5
10 20

Sample Output

6
30

#include<bits/stdc++.h>
using namespace std;
int main()
{
    long long n,a,b;
    cin>>n;
    while(n--)
    {
        cin>>a>>b;
        cout<<a+b<<endl;
    }
}
