Why should the private member functions in a class almost always have void returns and no inputs?
What will be an ideal response?
The private class functions can see and access the class data directly, so there is no need to pass anything into them or have them return anything. They’ll work on the class data. The need to pass into class functions and pass data out of class functions arise from the “world’s” interaction with the object. When the world need to give the object data, it should be passed into the public set functions. The public get functions will return values to the world.
