Problem: Pointer

Link to the Challenge:

Source Code

#include <iostream>
using namespace std;

int a;
int b;
int sum;
int difference;

void addSubtract() {
    cin >> a >> b;

    sum = a + b;
    
    if (a >= b) {
        difference = a - b;
    } else {
        difference = b - a;
    }
}

int main() {
    addSubtract();
    cout << sum << endl;
    cout << difference << endl;

    return 0;
}
