All right? And if you want to do other things, whoops, sorry-- and add them together, we will get out, again, a concatenation of that string. And these will, we'll let you work through the variations, but these are the simple expressions we can use.
对不对？如果你想要进行一些别的操作，哦，对不起-是加到一块，然后结果值也是，两个字符串的链接，这些会，我们会让大家慢慢学习变量，但是这些是我们能用的最简单的表达式。

But that little short hand there is doing exactly the same thing. It is adding that value into some digits and putting it back or signing it back into some digits. And I'll walk through that loop and when I'm done I can print out the total thing does. And if I do that, I get out what I would expect.
加上得到的这个数的,但是这个缩写声明其实是进行了同样的操作,它把我们得到的这个数加到一个数上面去,然后用和对这个数进行了重新赋值,在循环中会去遍历字符串，当完成循环后,程序会显示数字的总和，如果我运行，这个程序的话，我会得到我期待的结果。

And it treats it as a string, it's simply getting me back 52*7 the value of that string, 52 times 7, rather than the value of it.

This was the special value that said to the computer string stops here and because you have that barrier given to you at the end of every string, just the most efficient way you can pass strings around is just by passing the address of their very first bytes, the location in RAM.

I'm doing a test there to say, x if the string x is less than the value of b, and x does not appear before b as strings, then I was going to do, oh, a couple of things, because they're at the same block level.
我正在做一个测试来看看，字符串,是不是小于b的值，而且x不在b之前作为字符串出现，如果是真的话我就要做，一系列的操作，因为他们是在同一个块等级上。
