Question

Create a Class to contain a customer order

Create attributes of that class to store Company Name, Address and Sales Tax. Create a public property for each of these attributes.

Create a class constructor without parameters that initializes the attributes to default values.

Create a class constructor with parameters that initializes the attributes to the passed in parameter values.

Create a behavior of that class to generate a welcome message that includes the company name.

Create a Class to contain a customer order detail row

Create attributes of that class to store Product Name, Price and Amount. Create a public property for each of these attributes.

Create a constructor without parameters that set all the attributes to an empty string or zero.

Create a constructor with parameters that sets all the attributes to the passed in parameters.

Create a behavior that, when provided a sales tax value, returns the total price for a detail row including sales tax.

Create a behavior that, when provided a product name, price and quantity, returns a single line order detail.

Initialize a Customer order object instance.

For a custom order detail line, prompt the user to enter a product name, price and amount (each separately). Initialize a customer order detail object instance with the values provided.

Repeats this two more times for a total of three customer order details.

Using the behavior in Customer Order, display the header information in the console.

Using the behavior in Customer Order Detail, display the three order detail lines in the console (each on a separate line).

Pause the console for a final user input before.
