Question
Banking Project Must be in C++ Design and implement a hierarchy inheritance system of banking, which includes Savings and Checking accounts of a customer. Inheritance and virtual functions must be used and applied. The following features must be incorporated: 1. The account must have an ID and customer’s full name and his/her social security number. 2. General types of banking transactions for both accounts, Checking and Savings: withdraw, deposit, calculate interest (based on the current balance, and if it was not modified, there will be no new interest), figure out the balance, and transfer funds (between the two accounts, from Checking to Savings and vice versa). 3. Savings restrictions: Become inactive if the balance falls less than $25, and under such situation, no more withdrawals may be allowed. A $1 charge for each transfer fund (to Checking account), with the first transfer is free. The monthly interest rate is 3.75%. 4. Checking restrictions: A monthly service charge is $5 (automatically be charged when Checking account was opened). A 10 cents charge for each written check, with the first check is free. A $15 charge for each bounced check (not enough funds). The monthly interest rate is 2.5%.
