Question

Struct PERSON Assignment

Outcomes:

Demonstrate the ability to create structs using typedef

Demonstrate the ability to create an array of structs

Program Specifications:

DESIGN and IMPLEMENT a program that will CREATE and use three different variables of type PERSON.

Create a struct using the typedef command for a DATE.

Create a struct for a PERSON with the following fields.

name [this will be a string]

birthdate [this will be a DATE]

gender [this will be a char]

annualIncome [this will be either float or double, your choice]

Create three variables of type PERSON. Create a function that populates the data for each person (all 3 of them). Create a function that outputs all data about each of the people in a nice formatted manner.

Data Validation:

All dates entered must be validated. Make sure you account for the number of days in each month, the fact that there are exactly 12 months and every four years there is a leap year.

The name for each PERSON will be stored in sentence case.

The gender will either be M, F, or O.

The annual income will between 0 dollars and 1 million dollars.

Submission Requirements:

Requirements will be same as the first assignment which will be the same for all future assignments except that you do NOT NEED a design tool for this assignment.

DO NOT:

Use global variables, in this or any program ever.

Use goto statement(s), in this or any program ever.
