The application will allow users to simulate beep sounds by pressing different keys on their keyboard. The default mode will be automatic, where the application will randomly generate beep sounds at different frequencies. In keyboard mode, users will be able to control the frequency of the beep sounds by pressing specific keys on their keyboard. Finally, in user-selected frequency mode, users will be able to input the frequency of the beep sound they want to simulate.
The application will be built using the C# programming language, utilizing the built-in System.Console.Beep() method to generate the beep sounds. Users will be able to switch between different modes using a simple menu interface, with options to start and stop the beep sounds as well.
The code will be well-documented and organized, with separate classes for each mode of operation, as well as a main program class to handle user input and output. The code will be uploaded to your Github repository for easy access and sharing with others.
