A class named clock has two instance variables: hours (type int) and isticking (type boolean). write a constructor that takes a reference to an existing clock object as a parameter and copies that object's instance variables to the object being created. your task: write a clock constructor that makes this possible. just write this constructor - - don't write the whole class or any code outside of the class!

You can use the initializer list for that; no code needed:

Clock (const Clock& rClock) : hours (rClock. hours), isTicking (rClock. isTicking)

{

/ / no code needed

}

In fact, the compiler will provide this copy constructor by default, you don't even have to write this constructor!
