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.)

有五个学生，每个学生有3门课的成绩，从键盘输入以上数据（包括学生号，姓名，三门课成绩），计算出平均成绩，况原有的数据和计算出的平均分数存放在磁盘文件"stud"中。(There are five students, each student has three classes of results, more than from the keyboard input data (including student number, name, class 3 results), calculated the average performance, the status of the original data and calculated the average score placed disk file in the " stud" in.)

可以读取从IGS网站上下载的电离层文件，并输出某一个网点上的电子含量值(Can be read from IGS ionospheric site to download files and output one dot on the value of electronic content)

说明：  形参只是形式参数，并不参与实际运算，但是形参在同一个函数里要相同，实参是实际参数，参与实际的运算， 有几个形参就对应有几个实参，形参在自定义函数里，实参在主函数里 (Formals only formal parameter is not involved in the actual operation, but parameter in a function to be the same, the argument is the actual parameters involved in the actual operation, several shape parameters corresponding to several arguments, parameter in Custom function, the argument in the main function)
