Question 4 Why are typedef statements useful? Group of answer choices A typedef statement is a new style statement.  It comes with a lot of new C++ library features. A typedef statement is an old style statement.  It allows us to access old programs without any  problem. A typedef statement allows for flexibility when the data type for an item needs to be modified for a program depending on the application. The data type may simply be modified in the typedef statement rather than in the entire program. A typedef statement allows for anonymousness when the programmer does not want to reveal the data type for an item to anyone. A typedef statement allows a consistent data type for a program. This will not allow  any data type change.

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.
