When the mouse is pressed, the coordinates of the mouse on the form are recorded, and a bool variable is used to record the state of the left mouse button press. When the left key is played, the Boolean variable that records the state is false.

Regardless of the type, all data is a series of bits, i.e. 0 and 1. The meaning of a variable is conveyed by explaining how these programs are interpreted. The simplest is the char type, which represents one character in the Unicode character set

First, Static classThe important difference between a static class and a non-static class is that a static class cannot be instantiated, that is, a variable of a static class type cannot be created with the New keyword. Using the static keyword when
