本书是由c语言的设计者brian w. kernighan和dennis m. ritchie编写的一部介绍标准c语言及其程序设计方法的权威性经典著作。全面、系统地讲述了c语言的各个特性及程序设计的基本方法，包括基本概念、类型和表达式、控制流、函数与程序结构、指针与数组、结构、输入与输出、unix系统接口、标准库等内容。 　　本书的讲述深入浅出，配合典型例证，通俗易懂，实用性强，适合作为大专院校计算机专业或非计算机专业的c语言教材，也可以作为从事计算机相关软硬件开发的技术人员的参考书。 在计算机发展的历史上，没有哪一种程序设计语言像c语言这样应用如此广泛(C language book is written by the designers of brian w. kernighan and dennis m. ritchie write a description of the standard c language and the authority of the program design classic. Comprehensive and systematic about the c language of all the basic features and programming methods, including basic concepts, types and expressions, control flow, function and program structure, pointers and arrays, structures, input and output, unix system interface, the standard library and so on. Book about simple terms, with a typical example, user-friendly, practical, suitable as a computer professional or computer professional colleges of the c language materials can also be as engaged in computer-related hardware and software technology developed by staff reference. In the history of computer development, no programming language such as c language so widely used)

说明：  内容：实验要求学生熟悉 LabVIEW 的编程环境，创建一个 VI 程序模拟温度测量，可 用摄氏也可用华氏显示温度，检测温度是否超出范围，当温度超出上限时，前面板上的 LED 将点亮(Content: the experiment requires students to be familiar with the programming environment of LabVIEW and create a VI program to simulate temperature measurement Use Celsius or Fahrenheit to display the temperature, and check whether the temperature is out of the range. When the temperature is out of the upper limit, the LED will be on)
