CMPS 221 - Lab 10

Lab 10 - Introduction to Classes

The purpose of this lab is to learn how to create a basic class object with member functions and a default constructor.

Program Requirements: Convert the structure from Lab 9 into a class. Your class will have the same member variables as the structure for Lab 9, but these variables will now be in the private section of the class. You will have the following three functions in the public section of the class:

Default constructor - This function will set the name, description and UPC C-style strings to the empty string (first character is the null character) and the number of products in stock to 0.
void printProduct() - This function will print all of the product information to the screen. Since it is a member function, it can access the member variables directly and will not need to be passed anything.
void getProduct() - This function will prompt the user for all of the product information and read it into the appropriate member variables. Since this is a member function, it can directly access the member variables and will not need to use the dot operator like you did with structures last week.

The main() function should be the following (copy and paste into your code). This assumes the class is called ProductObject. Update with the class tag that you used for your class.

int main()
{
  ProductObject p1, p2;

  cout << "Enter the information for product 2...\n";
  p2.getProduct();

  cout << "\nProduct 1 (default values) information is:\n";
  p1.printProduct();

  cout << "\nProduct 2 (user-supplied values) information is:\n";
  p2.printProduct();

  return 0;
}

When the program is run, it should resemble the following (the user input is in blue font face):

Enter the information for product 2....
Enter product name: red ball
Enter product description: A small red spherical toy.
Enter UPC code: 12497438956
Enter quantity in stock: 15

Product 1 (default values) information is:
Name:               UPC:                Stock: 0
Description: 

Product 2 (user-supplied values) information is:
Name: red ball      UPC: 12497438956    Stock: 15
Description: A small red spherical toy.
