This program declares a class called Inventory that has itemnNumber (which contains the id number of a product) and numOfItem (which contains the quantity on hand of the corresponding product)as private data members.
The program will read these values from a file and store them in an
array of objects (of type Inventory). It will then print these values to the screen.
Example: Given the following data file:
986 8
432 24
This program reads these values into an array of objects and prints the following:
Item number 986 has 8 items in stock
Item number 432 has 24 items in stock

void getAmount(int num); // This puts num in the private data member // numOfItem of the object that calls it.
};
void display();
// This prints to the screen
// the value of itemNumber and numOfItem of the // object that calls it.
// This is an id number of the product // This is the number of items in stock
