1. The program must be in C#
2. Create an Enum and call it Item. Declare 20 values in the Enum and name them based on your preference. Create a structure called Order. Declare an Item and a double for the item price. Create a structure called Package where it has an Order pointer, integer for the size, string for the address, package id and bill details. In the main, declare a Package and assign to it more than 3 items. Create a string returning function called generateBillDetails that takes a Package as constant reference and return the bill details as string. Dont create a string variable/object in the main or outside the main to store the returned value. Store the returned string in the Package. Show the bill string on the console.
