This textbook was developed in response to the growing scale of Sino-Foreign education cooperation and the growing demand for English and bilingual textbooks. It focuses on students participating in English or bilingual classes in higher vocational education, and emphasizes the combination of theory and practice.
This textbook provides a variety of resources, such as the Chinese annotation of the corresponding chapters, answers to the exercises, source codes, teaching coursewares, teaching plans and other conventional teaching resources. Students can scan the QR code to gain these resources.
The C language is a popular computer programming language. It is a very important basic course for students of electronics, computers, automation, communication and other majors. The C language is a compulsory course for students majoring in electronics and computer applications. Internationalization and Sino-Foreign cooperation in higher education have been important trends in recent decades. In this context, there is a growing demand for English and bilingual textbooks, and it is difficult to locate English textbooks suitable for Chinese students in the market. This textbook was produced for students from foreign cooperative education and bilingual courses in higher vocational education, fully considering the learning characteristics of higher vocational students, and focusing on the combination of theory and practice.
Features of this textbook are as follows:
1) Written in English and proofread by foreign teachers.
Due to developing of Sino-Foreign cooperation and the internationalization of higher education through foreign teaching, all English classes and bilingual classes are increasingly widely-offered in colleges.?Higher vocational education requires progressively more English and bilingual textbooks. This textbook is written in English, and its contents were supervised and reviewed by professional foreign teachers, which ensured the accuracy and professionalism of the English communication of the contents.
2) Emphasis on practice.
By considering the learning characteristics of higher vocational students, the contents of this textbook have been arranged in a way that promotes “learning by doing, doing by learning”. Each example has a detailed analysis, so that the knowledge of the theory can be strengthened. Students can understand how to analyze and solve practical problems, and gradually cultivate good programming habits.
3) Logical and well-ordered content.
In order to enable students to learn the C language effectively, the contents of the textbook have been designed to be structurally logically, and ordered in such a way that the level of learning follows a scaffolding approach. According to the characteristics of the C language, the chapters have been arranged?from an elementary?level to?an advanced level. For each chapter, the theoretical knowledge has been used as a guide, followed by an example analysis and programming practice, and finally, the knowledge is extended through the presentation of more complex theory.
4) Dual teaching resources.
This textbook provides a variety of resources, such as the Chinese an notation of the corresponding chapters for students with a less-developed English level. Additionally, exercises answers and example source code for students’ self-study, e-textbook courseware and e-teaching plans for teachers’ have been provided. Students can scan the QR code to gain these resources.
There are 12 modules in this textbook. The contents of each chapter are written in English, including: C programming overview; types, operators and expressions; input and output; decision making; loops; arrays; functions; preprocessors; pointers; structures, unions and enums; bitwise operators and files.
All of the teachers who participated in the production of this textbook have many years of professional experience. Modules 1, 2, 6, 9 and 10 were written by Liao Renxiu; Modules 3, 4 and 5 by Wang Weibin; Module 7 by Lin Jie; Module 8 by Zhang Ying; and Modele 11 by Zhu Suhang; Module 12 by Chen Guilan. Liao Renxiu and Wang Weibin were responsible for the organization and compilation of the contents. Lloyd Michael Hasson provided proofreading for the whole manuscript to ensure the accuracy and professionalism of the English language used in this edition.
However, due to various limitations and a constrained development time, there will inevitably be omissions in the textbook. We hope that readers will provide corrections if necessary.
