In the past half hour, I've started learning C++. As a project, I decided to try and write a program that will turn a fraction into a percentage. Here is my code: Code: #include <iostream> using namespace std; int main() { int numerator, denominator, quotient; cout << "Percentage Calculator\n"; cin.get(); cout << "Enter numerator: "; cin >> numerator; cout << "\nEnter denominator: "; cin >> denominator; cin.get(); cout << numerator << "/" << denominator << " = "; quotient = numerator/denominator; cout << quotient * 100 << "%"; cin.get(); } For some reason it doesn't like the division, could anyone tell me what I'm doing wrong? Thanks

Of course it doesn't work since your quotient variable is set to integer, and therefore cannot have a float value! What you need to do is replace the following: (1) int numerator, denominator, quotient; with int numerator, denominator; float quotient; (2) quotient = numerator/denominator; with quotient = (float)numerator/denominator; Now it should work!
