Programming Project 2

Bank Account

Out: Wednesday, April 9

Due: Wednesday, April 16, before 11:59 p.m.

The Objective

This project is designed to give you practice working with switch statements and functions. It will also give you more practice working with while loops.

The Background

Most people store their money in a checking account. There are two basic operations performed on the checking account. One operation is to deposit money into the account and the other is to make a withdrawal from the account.

The Task

Your job is to write a program that will simulate the behavior of a checking account. Your program should accept a beginning balance from the user and then display a menu with four options. The menu should have the four options shown in the sample output below. The functions you will write, in addition to the main function, are:

Hints

Note that functions like withdrawal() and deposit() update the balance and return it. Recall that function parameters are local variables, so just updating the balance parameter variable inside these functions will not change the balance in the calling function. So, the function that calls withdrawal() and deposit() (probably main()) must take the return value and assign it back into the balance variable it is maintaining.

Sample Output
