1. What is a const?A constant type is a type that uses the const description of a type modifier, and the value of a variable or object of a constant type cannot be updated. (Of course, we can rescue to update:)2. Why is const introduced? The initial

In the previous article, we described how this state machine model is used. By example, we find that we can use this model to quickly build a state machine that meets basic business needs. In this paper, we will parse the basic code of the model so
