C语言是一种计算机程序设计语言,它既具有高级语言的特点,又具有汇编语言的特点。它的功能性非常强大,目前是各高校的一门必修课。并且市场上许多软件也是基于C语言的平台而产生的,所以C语言在大学中的教学也称得上是"不遗余力"。但是近些年很多的学生普遍反映C语言晦涩难懂,不容易学透,非常努力的学最后却得不能心满意足,课程过后一无所获,甚至一个小小的程序都写不出来,于是针对这些情况就做出一些初步的分析,并且从C语言编程技巧上提出相关的改善对策。 (C language is a computer programming language, both with advanced language features, but also has characteristics of assembly language. Its function is very powerful, is now a required course in colleges and universities. And also a lot of software on the market based on the C language, platform and produce, so C language teaching at the university is also described as a "spare no effort." But in recent years, a lot of students generally reflect the C language obscure, not easy to learn thoroughly, very hard to learn, but finally could not have satisfied the course after nothing, even a small program that can not write, so for these situations to to make some preliminary analysis, and from the C programming language skills relevant improvement measures put forward.)

说明：  (1)把该字符串传送到附加段中偏移量为GET-CHAR开始的内存单元中。 (2)比较该字符串是否与“The Computer”相同,若相同则将AL寄存器的内容置1,否则置0。并要求将比较次数送到BL寄存器中。 (3)检查该字符串是否有“&.”符,若有则用空格符将其替换。 (4)把字符串大写字母传送到附加段中以 CAPS 开始的单元中,其余字符传到以CHART开始的单元中。然后将数据段中存储上述字符串的单元清0。((1) The string is passed to the memory unit in the additional segment whose offset is the start of get-char. (2) Compare whether the string is the same as "the computer". If it is the same, set the content of Al register to 1, otherwise set it to 0. The comparison times are required to be sent to BL register. (3) Check that the string has a "&." character, and if so, replace it with a space character. (4) The uppercase letters of the string are transferred to the cells starting with caps in the additional segment, and the rest of the characters are passed to the cells starting with chart. Then, the unit in the data segment that stores the above string is cleared to 0.)
