Explanation

In the above program, we created a class Demo that contains two static methods ReadDrives() and Main().

In the ReadDrives() class we read available disk drives and print the disk name, disk type, and size of the disk in GigaBytes on the console screen using DriveInfo class. 

The Main() method is the entry point of the program, here we called the static method ReadDrives().
