#include<iostream>
#include <stdexcept>

int divide(int a, int b) {
    if (b == 0) {
        throw std::invalid_argument("division by zero");
    }
    return a / b;
}

int main() {
    int a = 10, b = 0;

        std::cout << "Result: "<< result<< std::endl;
    } catch (const std::invalid_argument& e) {
