A typedef is a C keyword that defines a new name for a data type, including internal data types (int, char, etc.) and custom data types (struct, etc.). A typedef is itself a type of stored class keyword that cannot appear in the same expression as the keywords auto, extern, static, register, etc.
Conditional compilation is static compilation of code based on the actual definition of macros (some kind of condition). Compilation conditions can be determined based on the value of an expression or whether a particular macro is defined. C language conditional compilation related precompilation instructions, including #define, #undef, #ifdef, #ifndef, #if, #elif, #else, #endif, defined.
Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly, procedural), object-oriented and functional programming. Python is often described as a “batteries included” language due to its comprehensive standard library.
Performance optimization methods and ideas for large C projects. Performance optimization strategies for x86 projects that encounter performance bottlenecks when porting to low performance processors.
GDB is a powerful program debugging tool based on command line under UNIX/LINUX operating system released by GNU Source Organization. For a C/C ++ programmer working on Linux, GDB is an essential tool.
Reduce page tables by increasing the size of operating system pages to avoid fast table misses. Large page memory optimizer is designed for malloc mechanism, which means allocating large pages to increase TLB hit ratio.
In development, we just need to know that lib is needed at compile time and DLL is needed at run time. If you want to compile source code, lib is all you need. If you want dynamically connected programs to run, you need only a DLL. This article will more clearly understand the difference, generation, use of the two.
Read the binary file (any file will do; this article uses binary as an example) and read the entire contents of the binary file into a char* string. With fseek() and fread() functions to achieve file reading advanced methods.
