【Abstract】 Function is the key and difficult point in learning C language. Through the analysis of the function structure, the problems that are difficult to determine in writing functions are decomposed and refined. According to the numbers of the return values of function, functions may be divided into three categories, functions with no return values, functions with one return value, and functions with multiple return values. The design method of three kinds of functions are analyzed and illustrated with examples. The concrete procedures about how to write functions are elaborated respectively.更多还原
