In the main() function, create an object of VisitingProfessor and invoke its member function display() to show total income and the number of courses he/she has been taught

Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.

Assume that you have created a class named MyClass. The header of the MyClass constructor can be ____________. public MyClass() public MyClass (double d) Either of these can be the constructor header. Neither of these can be the constructor header.

(General math) a. Construct a class named Cartesian containing two double-precision data members named x and y, which will be used to store the x and y values of a point in rectangular coordinates. The member functions should include a constructor that initializes an object’s x and y values to 0 and functions to input and display an object’s x and y values. Additionally, include an assignment function that performs a memberwise assignment between two Cartesian objects. b. Include the class written for Exercise 2a in a working C++ program that creates and displays the values of two Cartesian objects; the second object is assigned the values of the first object.

What is the difference between a friend function of a class and a member function of a class? (3)

A(n) ____________ is one instance or variable of a class.

Mark the following statements as true or false. a. In single inheritance, a base class can create only one derived class. (1) b. The public members of a base class can only be inherited as public members in the derived class. (2) c. To redefine (or override) a member function of the base class in the derived class, the corresponding member function must have the same name, number, and type of parameters. (3) d. If the derived class does not override a public member function of the base class, you may specify a call to that public member function by using the name of the function and the appropriate parameter list. (3) e. The constructor of a derived class can specify a call to the constructor of the base class in the heading of the function definition. (4) f. The constructor of a derived class can specify a call to the constructor of the base class using the name of the class. (4) g. Suppose that x and y are classes, one of the member variables of x is an object of type y, and both classes have constructors. The constructor of x specifies a call to the constructor of y by using the object name of type y. (4) h. When the destructor of the derived class executes, it automatically invokes the destructor of the base class. (5) i. The class ios is the base class for all stream classes. (7) j. In protected inheritance, the private members of the base class are protected members of the derived class. (8) k. In composition, one or more members of a class are objects of another class type. (9)
