The struct and class definitions for Person should be expanded so that a Person besides having a birthday, also has a Date for when their height and weight was measured. Youll need to edit both the class and struct descriptions as well as the main functions which exercise them.

You will modify the StructOne.cpp and ClassOne.cpp files so that they produce output like that in the Listings at the end of this document. This is where you need to do the planning.

1. This dialog demonstrates the desired operation of StructOne.cpp source code when modified to include this new capability, now referred to as Lab03 struct.cpp.

Enter month as integer 1-12: 3

Enter day as integer 1-31: 21

Enter year as integer: 2002 Printing the dates:

10/6/2000

3/21/2002

Birthday:

Enter month as integer 1-12: 5

Enter day as integer 1-31: 10

Enter year as integer: 1991

Measure date:

Enter month as integer 1-12: 10

Enter day as integer 1-31: 6

Enter year as integer: 1962

Joe was born in 1991

Height is 72

Weight is 180

Last measured on 10/6/1962

Birthday is 5/10/1991

And here is Fred.

Height is 74 Weight is 200

Last measured on 6/21/2007

Birthday is 11/27/1968

2. The following dialog demonstrates the desired operation of ClassOne.cpp source code when modified to include this new capability, now referred to as Lab03 class.cpp.

H:\Temp\Lab03_class\Debug> Lab03_class.exe

Enter month as integer 1-12: 3

Enter day as integer 1-31: 21

Enter year as integer: 2002

Printing the date:

3/21/2002

Birthday:

Enter month as integer 1-12: 5

Enter day as integer 1-31: 19

Enter year as integer: 1993

Measure date:

Enter month as integer 1-12: 10

Enter day as integer 1-31: 6

Enter year as integer: 1962

Joe was born in 1993

And here is Joe:

Height is 72

Weight is 180

Last measured on 10/6/1962

Birthday is 5/19/1993

Joe was last measured in 1962
