The document discusses object oriented programming concepts in C++. It contains 4 questions with solutions. Question 1 defines a BankAccount class with data members like name, account number etc. and member functions to assign values, deposit, withdraw amounts. Question 2 overloads the increment operator ++. Question 3 overloads the > operator to find greater of two class instances. Question 4 demonstrates single and multiple inheritance - single inheritance defines a PhysicalFit class derived from BasicInfo class, multiple inheritance defines a DerivedD class derived from 3 base classes.

Q 1) Define a class to represent a bank account. Include the following members:
Data Members:
 Name of the Depositor
 Account Number
 Type of Account
 Balance amount in the account
Member Functions:
 To assign the initial values.
 To deposit an account.
 To withdraw an amount after checking the balance.
Write a C++ main program to display account number, name and balance.
