Write a C++ program that determines whether the user entered an item number in the required format: three digits, a hyphen, two digits, a hyphen followed by 4 alphanumerics. Display an appropriate message indicating whether the format is correct or incorrect. Use a sentinel value of -1 to end the program. You must use at least two functions in the solution of this exercise. Enter the item number Three digits, a hyphen, two digits,a hyphen, 4 alphanumeric characters Enter the item number (no spaces) or -1 to exit ==>123 You must enter a 11 digit item number Enter the item number Three digits, a hyphen, two digits,a hyphen, 4 alphanumeric characters Enter the item number (no spaces) or -1 to exit ==>123-45-abcd your Enter the item number Three digits, a hyphen, two digits,a hyphen, 4 alphanumeric character Enter the item number (no spaces) or -1 to exit ==>123-45-asc$ Item number must have four alphanumberics after second hyphen Correct the item number and reenter it Enter the item number Three digits, a hyphen, two digits,a hyphen, 4 alphanumeric characters Enter the item number (no spaces) or -1 to exit ==>-1 Program is terminating Thank you for using this program item number is well formatted s C:\csc134\Format\Debug\Format.exe (process 13040) exited with code 0.

When passing a C-style string as a parameter to a function - is the parameter passed by reference or default?

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.
