The correct answer is: A. You typically use a public member function to change the value in a private data member.
A public member function is a function that can be accessed by any code that uses an object of the class. A private data member is a data member that can only be accessed by the member functions of the class. Therefore, you cannot use a public member function to change the value in a private data member.
Here is a brief explanation of each option:
- A. You typically use a public member function to change the value in a private data member. This is false because a private data member can only be accessed by the member functions of the class.
- B. Because the constructor function does not return a value, you place the keyword void before the constructor’s name. This is true. A constructor is a special function that is called when an object is created. It is used to initialize the object’s data members. A constructor does not return a value.
- C. The public member functions in a class can be accessed by any program that uses an object created from that class. This is true. The public member functions in a class are accessible to any code that uses an object of the class.
- D. An instance of a class is considered an object. This is true. An instance of a class is an object that is created from the class.
