CASE1://This block code can no longer declare variables, if you declare the variable will be an error, unless enclosed in parentheses, this is a compiler problem, it can be said that the C language provisions. When you write code, pay attention to it. Just like the C language can not be assigned at the time of declaration, just remember. I hope to be of some help to you.
