Abstract:

Aiming at the status quo of difficulty to understand and grasp the essence of the C language function in the students’ learning process, Starting from the teaching practice and using the method of analogy, a C programming language function teaching process and method were designed from the perspective of producers and users in this paper. With the function application demand, the function was divided into calculation, judgment and operation classes. Several factors which the programmer should pay attention to by the time of function definition and call were discussed separately, such as the function interface specification, the function body, parameters, etc.

Key words: C programming language;function;producer;user
