Question

Hi so our professor is making us re engineer this code but so confuse about it for c++ and yes I'll rate you up thank you^^

re-engineer the code to handle the case of (milk <= 0)

with exception handling.

#include

using namespace std;

int main() {

int donuts, milk;

double dpg;

cout << "Enter number of donuts:\n";

cin >> donuts;

cout << "Enter number of glasses of milk:\n";

cin >> milk;

if (milk <= 0) {

cout << donuts << " donuts, and No Milk!\n"

<< "Go buy some milk.\n";

} else {

dpg = donuts/static_cast(milk);

cout << donuts << " donuts.\n"

<< milk << " glasses of milk.\n"

<< "You have " << dpg

<< " donuts for each glass of milk.\n";

}

cout << "End of program.\n";

return 0;

}

#include <iostream>

using namespace std;

int main() {
    int donuts, milk;
    double dpg;
    cout << "Enter number of donuts:\n";
    cin >> donuts;
    cout << "Enter number of glasses of milk:\n";
    cin >> milk;
    try {
        if (milk <= 0) {
            throw "Error";
        } else {
            dpg = donuts / static_cast<double>(milk);
            cout << donuts << " donuts.\n"
                 << milk << " glasses of milk.\n"
                 << "You have " << dpg
                 << " donuts for each glass of milk.\n";
        }
    } catch (...) {
        cout << donuts << " donuts, and No Milk!\n"
             << "Go buy some milk.\n";
    }
    cout << "End of program.\n";
    return 0;
}
