In this code, you start by declaring a file pointer to standard input so that you can get interactive information from the keyboard during the spell-check process.
这些函数必须在流打开后被调用（很明显，因为每个函数都需要一个有效的文件指针作为它的第一个参数），但是在对流有任何操作之前。
These functions must be called after the stream has been opened(obviously, since each requires a valid file pointer as its first argument) but before any other operation is performed on the stream.
