Deep Analysis of C Language

C Compile and link

The detailed process of compiling link, the structure of compiler, the format of object file, the memory structure of c program, etc.

C precompile

Macro definition, conditional compilation, code cross platform, special precompiled keywords, predefined macros, header file inclusion, etc.

Storage class, life cycle, scope, link domain

Review c memory image, storage class and auto/static/register keyword, instruction/constant/variable life cycle, variable and function scope, link domain and extern/static, etc.

Pointer and function

Pointer type, primary and multi-level, wild pointer and segment error, void *, const and pointer, function call, callback function and function pointer array, pointer and parameter transfer, recursive function, inline function, etc.

Make C library and c standard library

The working principle of library, the basic introduction of static library and dynamic library, the production of static library and dynamic library under linux, the production of static library and dynamic library under windows, the composition structure of c standard library, etc.

Array, string

Array overview, one bit array, two-dimensional array, multi-dimensional array, use malloc to create multi bit array, string, pointing to the formal parameters of variable/string/array and sizeof, main function, etc.

Structure, Consortium, Enumeration

Structure initialization/value assignment/parameter transfer, structure alignment, structure encapsulation function pointer and code hierarchy, common body, enumeration, etc.

Miscellaneous - knowledge that cannot be organized independently in c language

Automatic type conversion, large and small end order, comma expression, typedef, byte/word/half word/bit width, compiler optimization, extern "C", program debugging, variable parameter function/variable parameter macro, the magic of do {} while (0), c embedded assembly, assertion, etc.

Bit operations and standard IO functions

Micro operations:&, |,~, ^, standard IO functions: fopen, fclose, fscanf, scanf, fgetc, getc, getcha, fgets, gets, freader and other standard IO caching problems.

C Additional knowledge - multithreading, network programming

Multi threading, network programming, database, data structure, sequence list, linked list overview, single linked list, double linked list, queue and stack, Linux kernel linked list, etc.
