C语言中的函数应用时易出现的错误

C语言程序完全由函数组成。除程序必须包含的main函数（主函数）和语言本身提供的库函数外，用户还可根据需要定义任意多个自己的函数。通过主函数调用其他函数（库函数，用户自定义函数），其他函数之间的相互调用，完成相应的程序功能。C语言程序一般是由大量的小函数而不是由少量大函数构成的，这样可以让各部分相互充分独立，并且任务单一。文章对函数在C语言中的应用时易出现的错误进行了分析。

Mistake Apting to Appear when the Function is used in Language C

C language procedure is totally made up of function. Except main f unction (main function) that procedure must include and language storehouse func tion that itself offers, users can also define a lot of one's own function acco rding to their needs. Transfer other function through main function (the functio n of the storehouse , user's self-defining function), transferring each other b etween other functions, finish the corresponding procedure function. C language procedure is generally by a large amount of small function instead of forming by a small amount of great function, can let every part sufficient independence ea ch other so, and the task is single . The mistake apt to appear has been analyze d at the time of the application of function in C language in this article.
