我的教授称它为假设函数。并且还说这个函数将任意输入流引用作为参数，然后从流中读取字符，直到它找到''a''。然后该函数应返回读取的字符数。
我很确定我知道如何计算字符数。它或多或少试图弄清楚如何使用find_a（）。
My professor called it a hypothetical function. And also said This function will take a arbitrary input stream reference as a parameter, then read characters in from the stream until it finds an ''a''. The function should then return the number of characters read.
I''m pretty sure i know how to have it count the number of characters. Its more or less trying to figure out how to use find_a().

啊！这意味着该功能实际上并不存在于任何真实的库中。你要想象这个功能。作为某些类的一部分在那里。
Ah! This means the function does not actually exist in any real library. You are to imagine this "function" being part of some class "out there".

所以要使用它，你需要知道1）你传递给它的东西，2）它对你传递给它的东西做了什么，以及3）什么它返回。然后你就可以弄清楚如何使用它。
So to use it, you will need to know 1) what you pass to it, 2)what it does to what you pass to it, and 3) what it returns. Then you can figure out how to use it.
