"C程序设计教程第二版第七章：程序结构与规则"

Chapter 7 of the "C Programming Tutorial (2nd Edition)" by Qian Neng, published by Tsinghua University Press, focuses on program structure. The program structure is the framework that allows a program to run, and the study of program structure is aimed at better expressing algorithmic ideas, ensuring compliance with compilation logic, and enhancing readability and maintainability. The learning objectives of this chapter are to understand C program structure through simple function calls and to master the rules and experiences of organizing programs in a rational way, as well as to grasp the basic methods for scaling up programs. The chapter covers the following topics: 1. Function Organization: This section discusses the organization of functions in a program. 2. Header Files: It explains the use of header files in C programming. 3. Global Data: This section focuses on the handling of global data in a program. 4. Static Data: It discusses the use of static data in C programming. 5. Scope and Lifetime: This part delves into the concept of scope and lifetime of variables in C programs. The accompanying teaching materials are in PowerPoint format, making it easier to read and operate. They are synchronized with the content of the textbook authored by Qian Neng, providing a comprehensive learning experience for students. Throughout the chapter, students will gain a solid understanding of the fundamental concepts of program structure in C programming, including how functions are organized, the importance of header files, handling global and static data, and the concept of scope and lifetime of variables. By mastering these concepts, students will be well-equipped to write well-structured and organized C programs that are not only efficient and scalable but also readable and maintainable. With a focus on practical application and real-world examples, the chapter equips students with the essential skills and knowledge required for successful C programming.
