Write a program that creates a class Square having data members as sides X and Y of Square. A

parameterized constructor to assign values to data members X and Y, Overload comparison operator

to compare side of two square class objects and display message in main that two of the square

objects are equal or not.

Write a complete program to create a class called Account with protected attributes such as account

number and balance. The attributes should be initialized through constructors. The class contains a

array of Account objects. The array size should be given by the user at run time.

Compare single, multiple and multilevel inheritance.

Create a class employee with four data members emp_ name, emp_salary, emp_scale, bonus.

Create the following members functions

A Constructor to assign initial values to data members.

getdetail O to initialize the data members

showdetail to display the values of data members

addbonus to add the bonus in salary. If emp scale is 17 or greater then add 30% of salary as a bonus

in salary, other wise if the scale is less then 17 the add bonus 15%.

withbonus following function will display the salary after adding the bonus.

Write a C++ program to simulate a Bank Account system using exception handling.

Create a class BankAccount with the following data members:

Acc name (string), Acc_num (string or int), and Acc_balance (float or double).

Add a constructor to initialize all data members. If the user tries to enter a negative balance, throw a

user-defined exception named NegativeBalanceException,
