for poor-quality code.) In fact, good code can be readable even without annotations, but proper annotations make the code more readable and maintainable.?? The fifth chapter is about code style. Modern Ides (integrated development environment) almost all have the function of code formatting code, you just need to set up the code style you use, in fact, not only the IDE, many advanced text editing tools can also be formatted according to the specified style of your code. What style of code is no

Some people find programming boring, and some people think it's fun. But every programmer has to keep up with the trend of programming languages. Most programmers learn to program from C, because C is the most common language used to write operating systems and applications. C Programming Notes These are some of the notes in the introductory course for C programming at the Washington Institute of Experiments. They were revised based on a supplemental note from the C programming language (beginn

C Run-Time library functionsC Run-time library functions are some of the basic functions supported by the C language itself, usually implemented directly by the assembler.API functionsAPI functions are functions implemented by the operating system to implement specific functions for user-friendly design of applications, and API functions are also implemented in C language functions.DifferenceThe difference between them is that the API function is for the operating system, and the C language runt

A generationThe run-time library is a library file that is required by the program at run time, usually in the form of a Lib or DLL.C Run-time libraries are C Run-time Library, born in the 1970s, is the concept of C and not the C + + language world , c programs need to run the functions of these libraries.C language is the so-called "small kernel" language, in terms of its language itself is very small (not many keywords, program flow control, data types, etc.). So, after the C language kernel w

H defines Sig[zz (z] [zz)]ign and Sig[zz (z] [zz)]DFL constants, stating RAJSE and signal two functions.Stdarg. H defines a macro that reads the function parameter table. (such as the Vprintf,vscarf function).Stddef. H defines some common data types and macros.STDIO. H defines the standard and extended types and macros defined

Therefore, after the C language kernel is developed, dennis Ritchie and Brian kernighan used C to rewrite more than 90% of UNIX system functions, and separated the most commonly used functions to form header files and corresponding libraries, c run-time library is formed in this way.3) subsequently, with the prevalence of C language, the C compiler manufacturers, individuals, and

In c89, void main () is correct. Brian W. kernighan and Dennis M. Ritchie use main () as the classic masterpiece of the C programming language (). In the latest c99 standard, only the following two definitions are correct:Int main ()Int main (INT argc, char * argv [])(Reference: ISO/IEC 9899: 1999 (E) programming versions-C 5.1.2.2.1 program startup) If you do not need to obtain parameters from the comm

For example, the indentation, such as the variable name method, different classes, different methods, each different, this program is very difficult to see. So once you've chosen a style, be sure to keep it consistent. If a project has a style, even if it does not conform to your own habits, it must be consis
