摘　　要：函数的定义与调用是C语言初学者的一个难点,用已知的数学知识去辅助理解未知的C语言函数知识,可以加速对新知识自定义C语言函数的学习过程,新知识可以反过来提升老知识的泛化能力。运用C语言编写了实现数学功能的三个函数,由易到难,从简单到复杂地定义和调用函数,取得较好的学习效果。Function definition and call is a difficult point for beginners of C language.Using known mathematical knowledge to assist in understanding unknown C language function knowledge can accelerate the learning process of customizing C language function with new knowledge,and the new knowledge can in turn improve the generalization ability of the old knowledge.Using C language to write three functions to realize the mathematical function,from easy to difficult,from simple to complex to define and call the function,get better learning effect.

关 键 词：C语言 函数定义 函数调用 迁移学习法
