And we won't wait here one hundred seconds for it to finish, but we're using the loop, we're updating a variable, and we're formatting it in a nice way.

我们将不会再这里等待100秒来等它完成,但是我们使用循环，我们更新一个变量，我们把它排成一个漂亮的格式。

Initialization. A very common bug is to initialize a variable. Go through a loop, and then forget to reinitialize it when it needs to be reinitialized again.

忘记初始化,忘记初始化变量是一个很常见的错误,运行完一个循环之后,当需要再次初始化时。

But notice unlike a for loop, if you want to declare a variable or increment or decrement to variable, you've got to do that yourself.

但请注意不像for循环，如果你想声明一个变量,或者变大或变小一个变量，你需要自己完成。

And then I run a loop in which I read something in, I check to see if it's the right type, if it is, I change that variable to say it's now the correct type, which means the next time through the loop, I'm going to say I'm all set and I'm going to bounce out.

因为我还没输入，然后我运行一个循环,循环内部我输入一些东西,然后看看是不是正确的类型,如果是的话我改变input，Ok为真，来证明输入数是正确的类型，这就意味着下一次运行这个循环的时候,就可以跳出循环继续执行了。
