swap I'm going to keep track of a little variable called swap, it's initially true, and as long as it's true, I'm going to keep going, but inside of the loop I'm going to set it to false, and only if I do a swap will I set it to true.

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。
