Greeting from the console

Create a C# console app that can greet users in three or more languages. The app should keep count of how many times a user has been greeted. And a count of how many different users have been greeted.

The app should prompt the user to enter a command.

Valid commands are:

• greet followed by the name and the language the user is to be greeted in,
• greeted should display a list of all users that has been greeted and how many time each user has been greeted,
• greeted followed by a username returns how many times that username have been greeted,
• counter returns a count of how many unique users has been greeted,
• clear deletes of all users greeted and the reset the greet counter to 0,
• clear followed by a username delete the greet counter for the specified user and decrement the greet counter by 1,
• exit exits the application,
• help shows a user an overview of all possible commands.

Your program should:

• be able to greet a user in at least three different languages,
• have a default language it greet users if no language is specified,
• keep count of how many times a specific username is greeted
• ignore case differences - commands are case insensitive and should work for both upper and lower case.

Notify the user of invalid commands.

Use:

• use Console.ReadLine() to read user commands from the console,
• make sure your code is tested using xunit
• use the same project structure as the unit test my bootcamp project.

Top tip decouple the command parsing and reading code form the commands code
