Here are the files I've made so far:

1. Add the following constructors:
   • Default - Set the values to 0.
   • Non-default that accepts 1 integer - Sets the dollar amount to that integer, sets the cents to 0.
   • Non-default that accepts 2 integers - Sets the dollar amount to the first, and the cents to the second.
2. Don't forget to use your setters so that you will get any error checking they do for free.
3. You should not change anything in main (or your functions from last time). All you need to do is add the contructors.
4. Don't forget to add your information to the makefile before tar-ing, and submitting.

Sample Output

The following is an example of output for this program:

Dollar amount: 10

Cents amount: 23

Default constructor: $0.00

Non-default constructor 1: $10.00

Non-default constructor 2: $10.23

Another example is:

Dollar amount: 3

Cents amount: -2

Default constructor: $0.00

Non-default constructor 1: $3.00

Non-default constructor 2: $3.02
