Question

Lance 1. Write a C++ program that manages a user's bank account. The program must but not limited to: (a) Display a menu for the user once the program runs. The menu display should be done through a user defined function with no parameters. The display should look like the below snapshot. (3 marks) ***********Welcome to the Bank Account Manager program helps you make cash withdrawals and deposits (b) Ask the user for his/her full name. (1.5 marks) (c) Ask the user for his/her account number. (1.5 marks) (d) Ask the user to enter the password. The password can include any character. You will need to declare the password in the beginning as a constant say A*B4. (3 marks) (e) If the password is matching the declared one then the user will be asked to enter his/her current balance. Otherwise, the user will be kicked of the program. (3 marks) After this the user will be asked to enter a choice. The choices are listed below: (1.5 marks) • Choice 1 → Cash Withdrawal (Not allowed to withdraw more than K.D. 1000) • Choice 2 → Quick Withdraw (No restrictions on the below limits) oa: K.D. 50 b: K.D. 100 oc: K.D. 250 O od: K.D. 500 • Choice 3 → Cash Deposit • Choice 4 → Show Balance • Choice 5 → Exit the Program • Any invalid choice entered will notify the user and ask him/her to enter a valid choice. (g) After the user does his/her choice the program must jump to one of five user defined functions. (2.5 mark for each function → Total of 12.5 marks) (h) Each user defined function is able to implement a choice. (i) The current balance must be always updated with every operation done. (2 marks) (2 marks) End of Assessment
