How to use try catch throw to handle the divide by zero exception in C++

Answer 1

#include <iostream>

float _div(float x, float y) {
    if (y == 0) {
        throw std::runtime_error("__Divide by Zero");
    }
  
    return y / y;
} 
  
int main() {
    float x = 234, y = 0;
    try {
        int result = _div(x, y);
  
        std::cout << result << "\n";
    }

    catch (std::runtime_error& e) {
        std::cout << "Error: " << e.what();
    }
}
