Write a program in C++ using templates to create a generic function with the name area with two arguments, which receives either integer or float data types. The generic function evaluates the following algebraic expressions. 2=2²-2ry+y² Print the value of variable c. Sample output 1: Enter two numbers: 2 3.5 area of numbers 2 and 3.5 1s: 2.25 Enter two numbers: 2.5 3 area of numbers 2.5 and 3 is: 0.25

This assignment is not graded, I just need to understand how to do it. Please help, thank you!

Create a c++ program to automate the point of sale system in a stationery store The program should be a menu-driven program that allows users to-Add information about stationery.-Update information about stationery.-View the different stationery in the store-Select multiple stationery from the list and determine the quantity to purchase.-Calculate the total and display the amount needed.-View the transaction history.-Exit from the program.An array structure should be used to keep a record of all stationery. Identify and determine the appropriate members of this structure. Your program can start with a few stationery records to initialize this array. Each record must be tracked with a pointer. Remember to update the number of records each time a purchase is made. Use a function to execute each option provided in the menu (except the exit option). Information about each transaction performed needs to be saved in a file. Your program should also consider data validation.
