C language is a general-purpose computer programming language, widely used. The design goal of C language is to provide a programming language that can compile, process low-level memory, produce a small amount of machine code, and run without any support of the operating environment in an easy way.
Although the C language provides many low-level processing features, it still maintains good cross-platform features. A C language program written in a standard specification can be compiled on many computer platforms, and even includes some embedded processors (single-chip or We call MCU) and supercomputers and other platforms.
C language is a process-oriented computer programming language, and is different from object-oriented programming languages ​​such as C++ and Java.
1, the program structure is simple, compact, regular, simple expression, flexible use.
2, the preparation of the program is readable, high compilation efficiency.
3, has a wealth of operators, up to 34 species. The combination of rich data types and rich operators makes C language expressive and efficient.
4, a wide range of data types. The C language has five basic data types, multiple construction data types, and composite export types. It also provides pointer machine operators that are closely related to addresses. Pointers can point to various types of simple variables, arrays, structures and unions, and even functions. In addition, C language also allows users to define their own data types.
5, is a structured programming language, especially for modular design of large programs. The C language has the basic flow control statements necessary to write a structured program. The C language program is composed of a set of functions, each of which is independent and serves as a basic unit of modular design.
The C language source files can be divided into multiple source programs, compiled separately, and then connected together to form a known target file, which provides great convenience for the development of large-scale software. C language also provides a variety of storage attributes, so that the data can be used in the corresponding scope as it needs to improve the reliability of the program.
6, grammar restrictions are not strict, program design freedom. For example, no cross-border of the array subscript is checked, and the programmer himself ensures that the program is correct. The general high-level language grammar check is strict, it can detect almost all grammatical mistakes, and C language allows the program writer to have a greater degree of freedom, thus relaxing the grammar check. Programmers should carefully check the program to ensure that it is correct, rather than relying too much on the C compiler to check.
7. Allows direct access to physical addresses, enables bit manipulation, and performs most of the functions of assembly language, allowing direct manipulation of hardware. Therefore, C language not only has the function of high-level language, but also is compatible with many functions of low-level language, and can be used to write system software.
8. The generated object code has high quality and high program execution efficiency. It is generally only 10% to 20% lower than the target code rate generated by the assembler.
9, has a high degree of portability. Its statement can basically be used for various types of computers and various operating systems without modification.
10. Any device that contains a microprocessor supports C language. From microwave ovens to mobile phones, they are all promoted by C language technology.

The popular language learning introductory books in China, many schools use it as a teaching material, for the C language is relatively easy to understand. However, some parts of the book are not rigorous enough and need to pay attention to some issues.
Second, advanced books recommended
1, TheCProgrammingLanguageSecondEdition
byBrianW.Kernighan,DennisM.Ritchie.PrenticeHallPTRC Programming Languages ​​Second Edition, New Edition.
This book is an authoritative classic written by C language designers Brian W. Kernighan and Dennis M. Ritchie, introducing the standard C language and its programming methods. A comprehensive and systematic description of the various features of C language and the basic methods of program design, including basic concepts, types and expressions, control flow, function and program structure, pointers and arrays, structure, input and output, UNIX system interfaces, standards Library and other content.
The book is written in a simple and ingenious way, with typical examples, easy-to-understand, practical, and suitable as a C language teaching material for college or university computer majors or non-computer majors. It can also serve as a reference book for technical personnel engaged in the development of computer-related software and hardware.
In the history of computer development, no programming language has such a wide range of applications as C language. The original book is one of the designers of the C language, Dennis M. Ritchie and the famous computer scientist Brian W. Kernighan co-authored an authoritative classic on the C language. We now see a large number of textbooks and monographs that deal with C language programming. The C language introduced in the first edition of the original book became the basis for the later widely used C language version, Standard C. The well-known "hell, World" program was first introduced by this book. Now, this program has become the first lesson in getting started with all programming languages. The original version 2 has been appropriately revised in accordance with the ANSIC standard established in 1987. The introduction of the latest language forms, and the addition of new examples, through a concise description, a typical example, the author fully, systematically and accurately describes the various features of the C language and the basic method of program design. For computer professionals, this book is a must-read reference book for programming languages.
2, PointersonC (C and pointer)
Highlight the importance of the pointer to C. Provide valuable tips and smart warnings.
This book provides comprehensive resources and in-depth discussions related to C programming. Through the discussion of the basic knowledge and advanced features of pointers, this book helps programmers integrate the powerful functions of pointers into their own programs.
The book consists of 18 chapters covering almost all important C programming topics such as data, statements, operators and expressions, pointers, functions, arrays, strings, structures, and unions. The book gives a lot of programming skills and tips, followed by highly specific exercises at the end of each chapter, and answers to some of the exercises are given in the appendix.
This book is suitable for C language beginners and junior c programmers to read, but also can be used as a computer professional students learn c language reference.
3, CTrapsand Pitfalls (C traps and defects)
Based on a thesis published in Bell Laboratories in 1985, the author combined his work experience to expand into a classic book that is valuable to C programmers. The starting point of writing this book is not to criticize C language, but to help C programmers to bypass the traps and obstacles in the programming process.
The book is divided into eight chapters, which analyze the problems that may be encountered in C programming from lexical analysis, grammatical semantics, connections, library functions, preprocessors, and portability defects. Finally, the author gives a number of practical suggestions with a chapter.
This book is suitable for C programmers who have some experience in reading and learning. Even if you are an expert in C programming, this book should be an essential book for your desk.
"C traps and defects" AndrewKoenigAndrewKoenig fame, can help beginners to reduce the 90% error. Some errors (such as assignments, operator precedence, etc.) may appear from time to time in their own programs. They have already been shot and are easily found.
4, ExpertCProgramming (C expert programming)
The "C Expert Programming" shows the coding techniques used by the best C programmers and has devoted a chapter to the basics of C++.
The book explains the history, language features, declarations, arrays, pointers, links, runtime, memory, and how to further study C++ and other issues in detail. The whole book draws dozens of examples to explain and has very high practical value for C programmers.
This book can help C programmers with certain experience to become experts in C programming. For programmers with a fairly basic C language, this book can help them stand on C's high level of understanding and learning C++ even if you read Andy Koneig's C traps and defects, you should still look at PeterVanDerLinden's book. I think that the books of both of them should be done in every possible way, as if they were plucked together. If I'm your supervisor, this is a necessary requirement.
5, CInterfacesandImplementations (C language interface and implementation)
This book has a clear concept, novel content, and detailed examples. It is a reference guide for designing, implementing, and effectively using C language library functions and mastering techniques for creating reusable C language software modules. This book advocates interface-based C language design concepts and their implementation techniques, and describes in depth 24 C language interfaces and their implementations. This book describes how to use a language-neutral approach to separate the design and implementation of an interface, thereby creating an interface-based design approach to creating reusable APIs. This book is a rare book for C programmers and is worth reading for all readers who want to master reusable software module technology.
