推荐答案

你应该研究这段代码在做什么，它意味着什么，我装备不是你所期望的。

You should study what this code is doing, what it means, I gear ot is not what you expect.

FriendsNames[1] == (Length % 2 == 0)

看起来你不是真正理解你的代码在做什么，使用调试器来看看它真正做了什么。



有一个工具可以让你看到你的代码在做什么，它的name是调试器。它也是一个很好的学习工具，因为它向你展示了现实，你可以看到哪种期望与现实相符。

当你不明白你的代码在做什么或为什么它做它做的时候，答案就是答案是调试器。

使用调试器查看代码正在执行的操作。只需设置断点并查看代码执行情况，调试器允许您逐行执行第1行并在执行时检查变量。

调试器在这里显示你的内容代码正在做，你的任务是与它应该做的事情进行比较。

调试器中没有魔法，它没有发现错误，它只是帮助你。当代码没有达到预期的效果时，你就会接近一个错误。

Looks like you don't really understand what your code is doing, use the debugger to see what it really does.

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
