C++ C-strings, structures, and file i/o

There are 2 parts to this project: 1) Write a program that simulates a soft drink machine. The program should use a structure that stores the following data: Drink Name Drink Cost Number of Drinks in Machine The program should create an array of five structures. The elements should be initialized with the following data: Drink Name Cost Number in Machine Cola 0.75 20 Root Beer 0.75 20 Lemon-Lime 0.75 20 Grape Soda 0.80 20 Cream Soda 0.80 20 Each rime the program runs, it should enter a loop that performs the following steps: A list of drinks is displayed on the screen. The user should be allowed to either quit the program or pick a drink. If the user selects a drink. he or she will next enter the amount of money that is to be inserted into the drink machine. The program should display the amount of change that would be returned and subtract one from the number of that drink left in the machine. If the user selects a drink that has sold out, a message should be displayed. The loop then repeats. When the user chooses to quit the program it should display the total amount of money the machine earned. Input Validation: When the user enters an amount of money, do not accept negative values, or values greater than $1.00. 2) Write a program that uses a structure to store the following inventory data in a file: Item Description Quantity on Hand Wholesale Cost Retail Cost Date Added to Inventory The program should have a menu that allows the user to perform the following tasks: • Add new records to the file. • Display any record in the file. • Change any record in the file Input Validation: The program should not accept quantities, or wholesale or retail costs, less than O. The program should not accept dates that the programmer deter- mines are unreasonable.
