#include <iostream>
using namespace std;

int main()

{
int a;
int b;
int sum = a + b;
cout << "Number";
cin << a;
cout << "Another number";
cin << b;
cout << sum
}

Answer 1

#include <iostream>
using namespace std;

int main()
{
// Always initialize numbers, otherwise you may
// end up having "garbage" value in a & b here.
int a=0;
int b=0;

// You haven't got user input yet, so calculating
// sum here is not the right thing to do
//int sum = a + b;

cout << "Number";
cin >> a; // Use >> operator for accepting input

cout << "Another number";
cin >> b; // Use >> operator for accepting input

// Now you have got the two numbers to add for,
// you can go ahead do the math.
int sum = a + b;
cout << sum; // You forget semicolon ; at the end
}
