Plzz refer the following solution for better understanding of the implementation.

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--)
	{
	  int a,b;
	  cin>>a>>b;
	  cout<<a+b<<endl;
	}
	return 0;
}

include
using namespace std;
int main()
int num1,num2,n,sum=0;
cin>>n;
for(int i=0;i<n;i++)
{
cin>>num1>>num2;
sum=num1+num2;
cout<<sum;
}
return 0;
}
