Write a complete C++ program as described below files are given to you. Please go through them on Titanium before beginning to program The cash register scanned item. Your program should code part of this logic. at a grocery store calculates the total bill by looking up the price of every The price of every type of item carried in the store is in a text file in the following format 23043 0.99 Apple 74001 0.79 Coke 10078 3.29 Eggs_ 6ct 0079 6.00 Eggs_12ct 4302 2.49 Milk iqt 59004 2.99 Bread wheat Column 1 is the item name, column 2 is the item code, and column 3 is the price in dollars. Implement your logic within a class GroceryBill. The class should have the following public member functions . GroceryBill: the constructor void readFile (string filename): a function which takes in the filename of the e data to its member variables. You should complete reading of pricelist an the file in this function (i.e., do not read the file outside this function) bool isValid(int itemcodes [ ], int nitems) : given an array of item codes return true if ALL the item codes are valid (i.e., appeared in the text file); it should return false otherwise. For example, if the array is: [34302, 10078, 34302], it should return true. ic member functions will be called from the provided main program and the answers ese publ rinted ther Th e (see file part2.cpp - do not change the contents of this file) empty file is provided) Item codes are integers Note that item codes can be repeated when scanning . You must implement all your code in one header file called GroceryBil1.h (an Simplifying assumptions: . Item names are a single word without spaces . Price is a float You do not need to do any error-checking when reading the data file
