Question

I am wondering how I can make the while loop work (In C++). It is supposed to keep asking to "Enter car's miles" until the input is valid, but right now if I enter in a wrong value then the system goes crazy and infinitely repeats "Enter car's miles"

if (vehicle=="car") { //input is a car

cout << "Enter car's miles: ";

cin >> entry;

while (!entry) {

cout << "Enter car's miles: ";

cin >> entry;

}

car_miles = car_miles+entry;

cout << "Enter car's gallons: ";

cin >> entry;

while (!entry) {

cout << "Enter car's gallons: ";

cin >> entry;

}

car_gallons = car_gallons+entry;

Explanation / Answer

while (!(cin >> entry)) { cin.clear(); cin.ignore(1024, ' '); cout entry)) { cin.clear(); cin.ignore(1024, ' '); cout
