Write a program that uses a structure to store the following inventory data in a file:
Item description
Quantity on hand
Wholesale cost
Retail cost
Date added to inventory
The program should have a menu that allows the user to perform the following tasks:
• Add new records to the file.
• Display any record in the file.
• Change any record in the file.
Input Validation: The program should not accept quantities, or wholesale or retail costs less than 0. The program should not accept dates that the programmer determines are unreasonable.
