Input and Output problem

[yabi2943993]

How can I stop an input and start an output after the input of two 0's?If the input is for example:
1 3
2 4
0 0
I want to stop the input after that 0. I tried to solve this problems with a while loop but I get a runtime error.
For example, if I want to add two numbers the output should be:
4
6

Post your code you wrote to solve the assignment.

And PLEASE use code tags. They make it MUCH easier to read and comment on source code.

In principle this is one way how you can do it.

It might have to be varied depending how your input actually works, ie 2 numbers at a time or 6 ... or even if it is only one zero or two zeroes that stop further input. Only you know so far.

#include <iostream>

int main()
{
    int number_1{0}, number_2{0};
    
    do{
        std::cout << "Enter 2 numbers: ";
        std::cin >> number_1 >> number_2;
        
        std::cout << number_1 << ' ' << number_2 << '\n';
    } while( number_1 != 0 or number_2 != 0 );
    std::cout << "THE END\n";
    
    
    return 0;
}

Enter 2 numbers: 1 3
1 3
Enter 2 numbers: 2 4
2 4
Enter 2 numbers: 0 0
0 0
THE END
Program ended with exit code: 0

#include <iostream>
int main() {
    for (int a, b; std::cin >> a >> b && (a || b); )
        std::cout << (a + b) << '\n';
}
