C语言中的函数与递归

英文原文

Functions are essential components of any program written in the C language. A function is a block of code that performs a specific task. Functions make code more modular and reusable, which is important for maintaining large programs. In C, functions can be defined within the main program or in separate files and included using headers. Recursion is a special case of function calls where a function calls itself either directly or indirectly. Recursive functions are often used to solve problems that have a repetitive nature, such as traversing tree structures or calculating factorials.

函数是用C语言编写的任何程序的重要组成部分。函数是一段执行特定任务的代码。函数使代码更具模块性和可重用性，这对于维护大型程序非常重要。在C语言中，函数可以在主程序内定义，也可以在单独的文件中定义并通过文件头包含进来。递归是一种特殊的函数调用情况，其中一个函数直接或间接地调用自身。递归函数常用于解决具有重复性质的问题，如遍历树结构或计算阶乘。
