C++ Operator Overloading

Question

I have 6 operator functions (+,-,*,/, istream, ostream)
The user has to enter 2 ratio numbers for adding subtracting multiplication etc.

How to call the operator if I had to select addition?
Do I need to create 2 objects to enter 2 ratio numbers?

Answer 1

You do :

ratio a,b;
cout<<a+b;
// Calls ratio's + overload.

// Assuming that your class is named 'ratio'...
