True or false: C++ class objects are always passed to functions by reference.

True or false: A class object can be passed to a function, but cannot be returned by a function.

Two or more functions may have the same name, as long as their ______ are different.

When a member function performs a task internal to the class and should not be called by a client program, the function should be made ___________.

When a member function forms part of the interface through which a client program can use the class, the function must be _____________.

Write a class named Car that has the following member variables:

• year. An int that holds the car’s model year.
• make. A string that holds the make of the car.
• speed. An int that holds the car’s current speed.

In addition, the class should have the following member functions.

• Constructor. The constructor should accept the car’s year and make as arguments and assign these values to the object’s year and make member variables. The constructor should initialize the speed member variable to 0.
• Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object’s year, make, and speed member variables.
• accelerate. The accelerate function should add 5 to the speed member variable each time it is called.
• brake. The brake function should subtract 5 from the speed member variable each time it is called.

Demonstrate the class in a program that creates a Car object, and then calls the accelerate function five times. After each call to the accelerate function, get the current speed of the car and display it. Then, call the brake function five times. After each call to the brake function, get the current speed of the car and display it.

In general it is considered good practice to have member functions avoid doing _________.

A class may only have one default _________ and one _________.

A class may have more than one constructor, as long as each has a different _________.

A constructor whose parameters all have default values is a(n) _________ constructor.

A destructor has the same name as the class, but is preceded by a(n) _________ character.

A destructor is a member function that is automatically called when an object is _________.

A(n) _________ constructor is one that requires no arguments.
