C++ please use C++ to code

Write a program with a function to read in the file parts.txt into either parallel vectors or a vector of structs. The data file is on ANGEL in zipped format. The first few lines of the file look like: P-13725 A 23 61.46 P-13726 B 12 51.08 P-13754 D 27 4.56 P-13947 ? 34 27.71 Representing part number, Class, On hand balance, cost. After the vector(s) has/have been filled, display a menu which allows the user to request the following reports . Total cost of inventory 2. A count of parts of each class 3. Cost of inventory for a class 4. Part with the highest cost of inventory s. Part with lowest cost of inventory 6. Exit. Each of these should be a function. I've posted a typical run on the next page Hints choice. Use system ("cls") to clear the screen after the user makes a There is a neat little trick you can use to count the classes based on the fact that the ascii value of 'A' is 65, 'B is 66, etc. Not necessary but very efficient! Here is the struct and the prototypes of the functions I used: struct Parts string number; char cls; int ohb; double cost; bool readFile (vector &pVector) int displayMenu ); double totalCost (const vector &pVector) void countByClass (const vector & pVector
