UNIT4

Objects and Classes

1. Define a class to represent a string with operations string length, compare and reverse. Show its use by writing main().

2. Write a program that demonstrates the Static Data Member And static member function.

3. Write a class called “arithmetic” having two integer and one character data members. It performs the operation on its integer members indicated by character member (+, -, *, /). For example * indicates multiplication on data members as d1 * d2. Write a class with all necessary constructors and methods to perform the operation and print the operation performed in format Ans = d1 op d2. Test your class using main().

4. Define Class named point which represents 2-D Point, i.e P(x,y). Define Default Constructor to initialize both data member value 5, Parameterized constructor to initialize member according to value supplied by user and Copy Constructor.Define Necessary Function and Write a program to test class Point.

5. Create a class Account. It has three data member account id, name and balance. Define function to assign value and display value. Define function that search account number given by the user. If account number exists, print detail of that account. Write a program using array of object. Declare at least 5 account and print details .

7. Write a program which include class to represent a vector 

(a serious of float values). Include member functions to perform the following tasks: 

a> To create the vector.

b> To modify the value of given elements.

c> To Display the given vector in the form(10,20,30).

8. Create a class ITEM with item_code, item_rate and quantity as a data members. Create an array of pointers to objects of class ITEM. Write a member function which will calculate the amount of item. Print item_code and amount of item.
