Stability of C programming principles

See http://blog.csdn.net/xpzhang/archive/2007/01/22/1489860.aspx for the latest version

1. Do not forget the initialization process for variables, especially pointers and arrays !!!

2. Do not treat unsigned char (INT) variables or arrays as char (INT !!!

3. Do not ignore if, else, default, and other special circumstances in switch !!!

4. Avoid non-bool results in the IF condition judgment while !!!

5. Try to avoid using malloc/free. Once used, try to implement matching malloc and free in the same function !!!

6. Do not ignore the processing of malloc failures. Do not forget to set the pointer to null after being free !!!

7. The function body should not be too large to avoid repeated writes.CodeWhich can be encapsulated as a function with independent functions !!!

8. Avoid using global variables in a functional function (a function that is written for a specific function and can be called repeatedly !!!

9. Do not ignoreProgramAny warning that appears during compilation !!!

10. Let your program code be read clearly and properly. Variable and function naming rules !!!

11. Put architecture design first, make it more detailed, give more time, and continue to modify and improve as needed !!!
