So, we know in this example the initial height should be 15 meters and the initial velocity should be 10, and for acceleration, I'm going to use -g and to keep life simple, I'm going to call it -10.

我们知道在这个例子中,初始高度为15米,初始速度为10,然后是加速度,我们用"-g"表示重力加速度,为了计算方便,加速度的值取为-10

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.

这是一个特殊的值，表示的是,字符串在这里结束，因为在每个字符串的末尾,都有那个关卡，这是一个最有效率的方式，你可以通过传递,字符串的第一个字节的地址来传递一个字符串，地址是在RAM中的。
