这是什么C语句，怎么办？ [英] What does this C statement do?

问题描述

伙计们，我的教授已指派我们涉及与数组，指针和函数输入一个任务。现在，你跳我与整个背部前，我们不会做你的功课你的事情，回答我的问题就不会解决问题。事实上，我已经在回答了我最好的猜测。我只是好奇，听听你想想这一点。

Folks, my professor has assigned us an assignment involving typing with arrays, pointers, and functions. Now, before you jump on my back with the whole "We aren't going to do your homework for you" thing, the answer to my question will not solve the problem. In fact, I've already taken my best guess at the answer. I am just curious to hear what you think about this.

下面是我得到的C语句：

Here is the C statement I was given:

double(*foo(double(*)(double,double[]),double))(double, ...);

我们的问题涉及描述foo的类型。我的问题很简单：这究竟是什么这个说法吗？至于我能读懂它，这是我见过code最混淆和不现实线任何一个，或者它实际上不是有效的C.让我知道你在想什么。

Our problem involved describing the type of foo. My question is simply this: What on earth does this statement do? As far as I can read it, this is either one of the most obfuscated and unrealistic lines of code I've ever seen, or it's not actually valid C. Let me know what you think.
