? (If so) Why? This is a very subtle question. Anyone should be congratulated on answering this question (the legitimate reason. The answer is: typedef is better.

The second example correctly defines the P3 and P4 pointers. 16. The C language agrees to some shocking structures. I

IOS miscellaneous pen-17 (stack area, etc.), ios-17 Stack): Automatically assigned by the system. It generally stores function parameter values and local variable values. Automatically created and released by the compiler. Its operation method is similar to the stack in the data structure, that is, the principle of first-in-first-out and first-out.

C/C ++ basic pen question 1.1.2 (solution of operator 10) and 1.1.2 I wrote an irresponsible blog post in the previous section and was trampled on it, causing a little loss.

In actual debugging, there are no four FD case
