Question

Write a program (C++) that shows Game sales. The program should use a structure to store the following data about the Game sale:

Game company

Type of Game (Action, Adventure, Sports etc.)

Year of Sale

Sale Price

The program should use an array of at least 3 structures (3 variables of the same structure). It should let the user enter data into the array, change the contents of any element and display the data stored in the array. The program should have a menu driven interface.

Input Validation: When the data for a new game sale is entered, be sure the user enters data for all the fields. No negative amounts should be entered for a “Sale Price” of the Game.

An example:

You will use 1 structure only and then manipulate that for working with the information.

The program should use an array of at least 3 structures (3 variables of the same structure).

An example of the structure:
struct Game
{
string name;
string type;
int year;
double price;
};

Code:
