- Book: C++ Programming: From Problem Analysis to Program Design 8th edition, D. S. Malik In C++ 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. Savings accounts: Suppose that the bank offers two types of savings accounts: one that has no minimum balance and a lower interest rate and another that requires a minimum balance and has a higher interest rate. Checking accounts: Suppose that the bank offers three types of checking accounts: one with a monthly service charge, limited check writing, no minimum balance, and no interest; another with no monthly service charge, a minimum balance requirement, unlimited check writing, and lower interest; and a third with no monthly service charge, a higher minimum requirement, a higher interest rate, and unlimited check…Asymptotic function relationships.
