So you can think of a new line as being rolling the paper up so you're on a new line but a carriage return moves the cursor or moves that writing head all the way back to the left.
你们可以把换行想象成翻纸,把回车当做是将光标,移动到最左边。
You should see that the blue line is better than the pink line because, for any expected return, the blue line is to the left of the pink line, right?
可以看到蓝线比粉线好,原因是对于任意的预期收益率,蓝线都在粉线的左边,对吧?
So we hit the curly brace so the very bottom of the function and as soon as you hit that, the next line in the story is well, then we return to main and where are we executing in main?
我们抵达花括号了,这是函数的末尾了,一旦到了那个地方,在下一行,然后返回到main函数中,在main中哪里开始执行?
You want to, for any given expected return, you want to minimize the standard deviation, so it's the left-most line and that means that everyone will be holding the same portfolio.
你希望,在期望收益固定的情况下,你肯定希望将标准差最小化,而这条线是最左边的线,这就意味着所有人,都愿意持有这样的投资组合。
And the reason that we now on the second line have the equal sign is because this function GetString has what's called a return value.
我们之所以,在第二行代码GetString前面加上等号,是因为这个函数会带回一个,返回值。
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。
X I'm passing an X, and yet I'm also assigning the return value to X. So just intuitively what's going to be the effect of this one line of code?
我传一个X,之后我把返回值赋值给,很明显,这一行代码,将会产生什么作用?
