Write a C++ programs to: 1. Create a class called Student with four (4) private member variables, name (string), quiz, midterm, final (all double type); 2. Include all necessary member functions for this class (at least 1 constructor, 1 get function, and 1 grading function - see #6); 3. Declare three (3) objects of Student type (individual or array); 4. Read from the keyboard three (3) sets of values of name, quiz, midterm, final and assign them to each object; 5. Using the object's member function to calculate the grade for each student (grade = quiz * 0.2 + midterm * 0.4 + final * 0.4) %3D 6. Display on the screen only the name of each student and the grade.

Assume the definition of class houseType as given in Exercise 11. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the member function set so that private members are set according to the parameters. b. Write the definition of the member function print that prints the values of the data members. c. Write the definition of the constructor of the class houseType so that the private member variables are initialized to according to the parameters. d. Write a C++ statement that prints the value of the object newHouse. e. Write a C + + statement that declares an object house of type newHouse, and initializes the member variables of house to "Ranch", 3, 2, 2, 2005, 1300, 185000, and 3600.0, respectively. f. Which function members are accessors and which are mutators?

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.

In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.

Consider the definition of the following class: (1, 2, 3, 5, 7) a. Give the line number containing the constructor that is executed in each of the following declarations. b. Write the definition of the constructor in Line 4 so that the instance variables are initialized to " ", " ", " ", 0, 0.0, and 0.0, respectively. c Write the definition of the constructor in Line 5 so that the string instance variables are initialized to"", and the other instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. d. Write the definition of the constructor in Line 6 so that the instance variables productName and manufacturer are initialized to the empty string, instance variable id is initialized according to the first parameter, and the remaining instance variables are initialized according to the last three parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. e. Write the definition of the constructor in Line 7 so that the instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative.

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