1. Define a class named MyClass. The class has two member variables varl and var2 Write the definition of the class, including: 1) Constructor 2) Methods that return values of varl and var2, respectively 3) Methods that set values of varl and var2, respectively. 4) __str_method that returns values of varl and var2 method that returns values of varl and var2 5) Outside the class, write code that creates an object of MyClass, say, obj, that initializes varl and var2 with user input values, respectively 6) Change varl and var2 of obj to var1 **2 and var2**2, respectively. 7) Print varl and var2 of the object. 2. In the above class (MyClass), overload___add___ __eq___ and _lt_operators as follow: a) sum = obj1 + obj2 sets sum. varl to be obj1. varl + obj2. varl, and sum. var2 to be obj1. var2 + obj2. var2 b) obj1 == obj2 only if obj1. varl == obj2. varl and obj1. var2 == obj2. var2 c) obj1

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 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.

Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)
