说明：  下面是一个结构体声明： struct box { char maker[40] float height float width float length float volume } a. 编写一个函数，按值传递box结构，并显示每个成员的值 b. 编写一个函数，传递box结构的地址，并将volume成员设置为其他三维长度的成绩。 c. 编写一个使用这两个函数的简单程序 (Here is a structure declaration: struct box {char maker [40] float height float width float length float volume } a. Write a function that is passed by value box structure, and shows the value of each member b . to write a function, passing the address box structure and volume settings for the other three members of the length of the results. c. use these functions to write a simple program)
