So inside of an instance, associated with an instance, we have both methods and fields.

还有一些内部变量，实际上我该这么说，我们通常把这些东西称为域。

I've got some internal variables I have to store, what kinds of things do I have to keep track of?

计算的时候需要占用多少内存,我需要存储一些内部变量,我需要记录哪些东西呢？

And when you declare a variable, whether as an argument or as literally a local variable, they only live inside of that function.

当你声明一个变量，不论是一个参数,还是一个局部变量，它们只存在函数的内部。

Again, I could have some other functions to compute things, but this is typically the place where I'm going to put them in.

注意这个声明典型的行为,就是为了定义了内部变量，以及类的内部特性,在说一次，我可以写一些。

What if I don't change the value of that variable inside of the code?

那么如果在循环内部,我不改变这些变量的值会怎么样？

All right. Second question: or maybe a better way of saying this, and the general format you're likely to see here is, a test involving a variable name, which must be initialized outside of the loop, and which interior to the loop gets changed, so that the test is going to change.

好，第二个问题：,换种更好的方式来说吧，你们通常喜欢的,方式是，这个测试涉及到一个变量名字，变量在循环外已经被初始化，然后循环内部会改变这个变量的值，因此测试结果会改变。
