#include <iostream>

using namespace std;

int main() {
        int a, b;
        char op;

        cout << "Enter operator: ";
        cin >> op;

        cout << "Enter first number: ";
        cin >> a;
        cout << "Enter second number: ";
        cin >> b;

        if(op == '+') {
                cout << "Result: " << (a + b) << endl;
        }
        else if(op == '-') {
                cout << "Result: " << (a - b) << endl;
        }
        else if(op == '*') {
                cout << "Result: " << (a * b) << endl;
        }
        else if(op == '/') {
                if(b == 0) {
                        cout << "Divisor can not be zero" << endl;
                } else {
                        cout << "Result: " << (a / b) << endl;
                }
        } else {
                cout << "Invalid operator!\n";
        }
}
