Summary of level 2 C test sites

1. Validity of variable naming
2. Data type conversion, including strong and implicit types
3. String: the Declaration, definition, and usage of a string, usually combining arrays and pointers
4. array: Conversion of the lower mark and sequential storage of the array
5. Functions: Declaration, definition, and call. recursive functions (such as the Philippine Naxi series) and function pointers (such as Callback functions)
6. variables: local, global, and static variables. Combined with functions, evaluate the value transfer, address transfer, and transmission methods of the two parameters.
7. pointer: Combined with functions, strings, and arrays, it should be noted that the pointer must be assigned a value before it can be used, unlike array declaration.
8. Operator inspection: Operator priority, combiner and bitwise operators, comma operators, and other special Operators
9. Three branch statements and their switch statements
10. Pay attention to the connection and difference among the three loop statements, as well as the difference between break and continue.
11. The structure and chain structure are mostly associated with pointers.
12. shared object: number of bytes occupied by the shared object
13. enumeration: the final value of the enumeration body
14. Basic Public Knowledge

PS: Level 2 C has been tested. Whether or not C is used as the foundation of programming language, you should keep in mind the knowledge points. You still have a lot of ambiguous knowledge points and need to spend some time on it.
