Tables and Coffee Tables Management System in C#

In this exercise, we will create a project named "Tables2," based on the existing "Tables" project. The project will include a base class "Table" that represents standard tables with a width and height. We will also introduce a derived class "CoffeeTable" that inherits from "Table" but includes a specific label indicating it is a coffee table.

Each table will have a method ShowData that prints its dimensions, while coffee tables will extend this method to add the phrase "(Coffee table)."

An array will be created to store 5 standard tables and 5 coffee tables. The sizes of the standard tables will be randomly generated between 50 and 200 cm, while coffee tables will have dimensions between 40 and 120 cm. All the tables' data will be displayed at the end.

Objective

1. Define a Table class with width and height attributes.
2. Implement a constructor to initialize the table dimensions.
3. Add a ShowData method to print the width and height.
4. Create a CoffeeTable class that inherits from Table.
5. Override the ShowData method in CoffeeTable to add the text "(Coffee table)."
6. In the Main method, generate an array with 5 tables and 5 coffee tables, each with random dimensions.
7. Display the data of all tables.

Create a project named "Tables2," based on the "Tables" project. In it, create a class "CoffeeTable" that inherits from "Table". Its method "ShowData", besides writing the width and height, must display "(Coffee table)."

Create an array that contains 5 tables and 5 coffee tables. The tables must have random sizes between 50 and 200 cm, and the coffee tables from 40 to 120 cm. Show all their data.

Table - Width: 90 cm, Height: 160 cm
Table - Width: 120 cm, Height: 130 cm
Table - Width: 75 cm, Height: 195 cm
Table - Width: 200 cm, Height: 180 cm
Table - Width: 100 cm, Height: 90 cm (Coffee table)
Table - Width: 80 cm, Height: 110 cm (Coffee table)
Table - Width: 50 cm, Height: 70 cm (Coffee table)
Table - Width: 60 cm, Height: 95 cm (Coffee table)
