Features: C language is one of the most popular programming languages in the field of computer software development. It is known for its powerful functionality, high efficiency, conciseness, flexibility, and portability, and is widely valued in the software development field. This book systematically and comprehensively introduces the methods of C language programming, divided into 11 chapters. The content includes various data types of C language (basic and composite), operators and expressions, various statements, functions, compilation preprocessing, and file operations. The book covers a comprehensive range of topics, with a well-structured organization. Through examples, it elaborates on the key points of C language syntax in detail, making it an invaluable textbook for learning C. This book is suitable for beginners learning C as well as experienced software developers seeking reference.
Chapter 1: Overview of C Language. Starting with an introduction to the development history and characteristics of C language, this chapter also includes examples to give readers an overall picture of C. It briefly covers the development process of C language programs, as well as the character set and lexical conventions of C.
Chapter 2: Basic Data Types. This chapter introduces fundamental knowledge in C programming language, including constants, simple variables, and basic data types, as well as two commonly used standard input and output functions.
Chapter 3: Operators and Expressions. This chapter covers expressions, the basic components of C language statements, and the operators used to construct them. It also discusses the precedence and associativity of operators.
Chapter 4: Statements and Control Flow. This chapter introduces various types of statements in C programs, including simple statements, selection statements, loop statements, and transfer statements.
Chapter 5: Functions. This chapter focuses on functions, which embody the structured design philosophy of C language. It covers the definition, declaration, function calls, nested function calls, and recursion.
Chapter 6: Variable Scope and Storage Class. This chapter discusses variable scope (local and global variables) and the four storage classes of variables (automatic, static, register, and external). It helps readers better utilize variables.
Chapter 7: Arrays. This chapter introduces arrays, an important composite data type in C, with a special emphasis on character arrays as a special case of arrays.
Chapter 8: Pointers. This chapter provides a detailed explanation of pointers, a key and challenging aspect of C language.
Chapter 9: Structures, Unions, and Other Types. This chapter covers two other composite types in C—structures and unions—as well as enumeration and bit-field types. It also explains how to use typedef to define aliases for existing types.
Chapter 10: Compilation Preprocessing. This chapter introduces a major feature of C language—compilation preprocessing—focusing on three key functions: macro definition, file inclusion, and conditional compilation.
Chapter 11: Files. This chapter primarily covers the standard input and output library functions related to file operations.
This book covers the main language points of C, providing a systematic and comprehensive introduction to the language. To help readers truly master C, we strive to explain each language point in a clear and accessible manner, especially highlighting common error-prone areas with detailed explanations and numerous examples. This enables readers to apply the language effectively. All example programs in this book have been tested and confirmed to run correctly on computers. Although these examples may not fully suit your specific application needs, they are sufficient for learning the language and mastering its key points. We hope readers can learn by example and develop their own applications.
