THIS IS THE QUESTION FROM C++ PROGGRAMING 5TH EDDITION D.S.MALIK. ch- 14 program exercise question # 5
Banks offer various types of accounts, such as savings, checking, certificate of deposits, and money market, to attract customers as well as meet with their specific needs. Two of the most commonly used accounts are savings and checking. Each of these accounts has various options. For example, you may have a savings account that requires no minimum balance but has a lower interest rate. Similarly, you may have a checking account that limits the number of checks you may write. Another type of account that is used to save money for the long term is certificate of deposit (CD). In this programming exercise, you use abstract classes and pure virtual functions to design classes to manipulate various types of accounts. For simplicity, assume that the bank offers three types of accounts: savings, checking, and certificate of deposit, as described next.
