1. Variable Division
2. member variables and local variables
3. Scope and lifecycle of Variables
I. variable definition
Data type variable name = value;
Ii. Variable Classification
Variables can be divided into two types based on their defined locations:
1. member variables: variables directly defined in the class
2. Local variables: variables defined in methods or code blocks

So summing up, the benefits of the Commission mainly have the following points:
1, save a lot of if...else ... or switch ... , making the program more object-oriented.
2, decoupling, the program is easier to expand. Example: Tracy.proxy interface Agent component, logging XML logs and Performance logs.
Of course, this is just an example of the benefits of using a delegate, but there
for the program. When executing a program, first find the main method, starting with the first sentence in the main method, and then the program ends when the main method is finished executing. A program can have only one main methodInput/Output
