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.

CODE:

OUTPUT:

Raw_code:

//includind stdio.h for input and ouput functions
#include<stdio.h>
//including string functions
#include<string.h>
//i implemented new functions for the code readability
//leap year function to check whether the given year in the date of birth is leap year or not
int leapyear(int);
//check_date function prototype to check the whether the given date is valid or not
int check_date(int ,int ,int);
//valid_gender function prototype to check whether the given gender is valid or not
int valid_gender(char c);
//sentence_case function prototype to check whether the given name in sentence case or not
int sentence_Case(char *);
//typedef is used to give new name for the existing name in c program
//DATE structure with 3 members for day ,month and year
typedef struct
{
   //integer variable for date
   int dd;
   //integer variable for month
   int mm;
   //integer variable for year
   int yyyy;
}DATE;//structure name DATE
//PERSON structure 4 members for name,date of birth that is another structure , gender and annual income
typedef struct
{
   //character array for name
   char name[30];
   //structure variable of date of birth this is best advantage of typedef we do not need to always specify the
   //struct structname structure_member just we need structure_name structure_member
   DATE dob;
   char gender[1];
   double annualIncome;
