Project Description: The management of a super store needs Customer Management System for registering customers based on some criteria. The system should allow registration management members to perform the following actions: Add customer record (id, name, age, gender and city) to the file. Print customer details (id, name, age, gender and city) Note: The purpose of this Project is to practice file input/output operations in c. Therefore, whenever you add a new customer record, you will be saving ALL the customer information into file. For example, each customer record will have an ID, a first name, a last name, age, gender and city. Project Details: The program will first ask the user to enter the customer registration year and number of customers in the year as shown in below sample: Welcome to the Customer Management System > Please enter the customer registration year (ex: 2017): 2021 > How many customers do you want to register in year 2021: 2 After the user enters the registration year and number of customers, the program should display the following main menu: Customer Management System * MAIN MENU* | A/a: Enter A or a for Adding a customer | D/d: Enter D or d for Printing customer Details | E/e: Enter E or e for Exiting the Program > Please enter your choice: If the user chooses A or a, then the program allows the user to enter the following information: customerID, first name, last name, age, gender, city. o Again, all information is to be stored in an file. • If the user chooses D or d, the program allows the user to print the customers details from file (read the array from file and display on the screen) • If the user chooses E or e, the program stop and display the message: > Thank you for using the Customer Management System!

Input validation
If the user enters incorrect choice for any menu, the program should continue to show the menu
and display the message "Invalid selection! Please try again".
If the user enters the age which is not in the range (15-90), the program should display the error
message "Invalid input! (age must be between 15 and 90)" and enforce the user to enter the
correct age.
If the user enters the gender other than "male or female", the program should display the error
message "Invalid input! (gender must be male or female)" and enforce the user to enter the correct
gender.

you add a new customer record, you will be saving ALL the customer information into file. For
example, each customer record will have an ID, a first name, a last name, age, gender and city.
Project Details:
The program will first ask the user to enter the customer registration year and number of customers in
the year as shown in below sample:
Welcome to the Customer Management System
> Please enter the customer registration year (ex: 2017): 2021
> How many customers do you want to register in year 2021: 2
After the user enters the registration year and number of customers, the program should display the

| D/d: Enter D or d for Printing customer Details
| E/e: Enter E or e for Exiting the Program
> Please enter your choice:
If the user chooses A or a, then the program allows the user to enter the following information:
customerID, first name, last name, age, gender, city.
o Again, all information is to be stored in an file.
• If the user chooses D or d, the program allows the user to print the customers details from file
