Question:
With the following:
friend int operator == (const cs303Point& point0, const cs303Point& point1);
in my .h file, how should the first line of the function definition look in the .cpp file?
Answer:
First of all, note that operator == returns a bool result rather than int. Therefore, it’s advisable to declare the function like this:
friend bool operator==(const cs303Point& point0, const cs303Point& point1);
As for the definition: simply copy the prototype, omitting the ‘friend’ keyword and the semicolon, open a pair of braces, and fill them with code:
// in the .cpp filebool operator==(const cs303Point& point0, const cs303Point& point1){ return ((point0.x == point1.x)&&(point0.y==point1.y));}
