"font-size: 14pt; line-height: 115%; font-family: "Times New Roman","serif";">

Could someone please help me with this assignment?

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Exercise 1: Give a C++ class declaration called SavingsAccount with

the following information:

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Operations (Member Functions)

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

1. Open account (with an initial deposit). This is called to put

initial values in

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

dollars and cents.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

2. Make a deposit. A function that will add value to dollars and

cents

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

3. Make a withdrawal. A function that will subtract values from

dollars and

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

cents.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

4. Show current balance. A function that will print dollars and

cents.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Data (Member Data)

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

1. dollars

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

2. cents

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Give the implementation code for all the member

functions.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

NOTE: You must perform normalization on cents. This means that if

cents is 100 or more, it must increment dollars by the appropriate

amount. Example: if cents is 234, then dollars must be increased by

2 and cents reduced to 34.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Write code that will create an object called bank1. The code will

then initially place $200.50 in the account. The code will deposit

$40.50 and then withdraw

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

$100.98. It will print out the final value of dollars and

cents.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

The following output should be produced:

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Dollars = 140 cents = 2.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Part 2: Change the program to allow the user to input the initial

values, deposit and withdrawal.

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Dollars = 370 Cents = 26

"font-size:12.0pt;line-height:115%;font-family: "Times New Roman","serif"">

Exercise 2: Replace the initial member function by two

constructors. One constructor is the default constructor that sets

both dollars and cents to 0. The other constructor has 2 parameters

that set dollars and cents to the indicated values.

"font-size: 12pt; line-height: 115%; font-family: "Times New Roman","serif";">

Have the code generate two objects: bank1 (which has its values set

during definition by the user) and bank2 that uses the default

constructor. Have the code input deposits and withdrawals for both

bank1 and bank2.
