Part 2: Write a program that will input miles traveled and hours spent in travel. The program will determine miles per hour. This calculation must be done in a function other than main; however, main will print the calculation. The function will thus have 3 parameters: miles, hours, and milesPerHour. Which parameter(s) are pass by value and which are passed by reference? Output is fixed with 2 decimal point precision.

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.
