Because I might have written some code in which I'm expecting that integer particular variable to have an integer value.
因为我可能写了一些代码,来把一些,变量的类型,指定为。
Right, so here's a little piece of code that's going to print out the smallest value of three.
好,那么这一小段代码,就是会显示出,三个值中最小的来。
So input is an int called F, print out to the screen or your piece of paper the value of C. Odds are you only need two, maybe three lines of code for this, but the goal ultimately will be try it on your own.
所以输入是一个int类型的F,在你的屏幕上,或你们的纸上打印出C的数值,可能你们需要两行或者三行的代码,但是最终的目标需要你自己独自尝试。
I'm much better having an exception get handled at the time of input than to let that prop -- that value rather propagate through a whole bunch of code until eventually it hits an error 17 calls later, and you have no clue where it came from.
不是我期望的格式,这时我最好有一个异常处理,而不是让其传下去,这个值传到代码的整个分支,最终会导致一个错误17调用的发生,并且你不知道这个错误是哪里来的。
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?
In temp. So that means at the end of that first line of code just as before the value of 1 ends A up in a variable called temp because we said go to A and I look around, oh, there's A, what's there?
在temp中,在第一行代码的末尾,值1最终到了叫做temp的变量中,因为我们指明了定位到,并且四处查看,哦,这里是A,里面是什么?
It becomes a 13 and that is consistent with the code and it also doesn't crash because now y has been assigned to the correct value.
它变成了一个13,这个和代码是一致的,程序也不会崩溃,因为现在y被赋了正确的值。
Now, the one that we're most interested in ANS is the one where, in fact, it gets out ANS, so you see down here in the code, there's a spot where it's going to return the value of ANS, which is what we want, right? That's the thing that holds the value that we intended to have.
现在我们最感兴趣的是这个,事实上它返回的是,所以你看这段代码,在这里返回ANS值,也就是我们想要的,对吧?,它就承载了我们想得到的值。
So don't underestimate the value for the next week or two of just inserting printf statements into your code temporarily just to print out what the value of some variable is, or some expression is, so that you can just do a sanity check.
所以不要低估下一两周的重要性,虽然我们只将“printf“语句暂时地植入到,我们的代码中,只是用来打印一些,变量或表达式的值,所以你们提醒一下自己。
So, after the second line for code here char * s1 gets the return value of get string this is what the state of our world looks like.
在第二行之后,这个代码char,*s1,等于GetSting的返回值,这就是它看起来的状态。
