It's only copying the address that was returned by get string so even though conceptually is the name this program suggests, I really just want to make a copy so that maybe I can make one version of D-A-V-I-D or F-O-O all uppercase or all lowercase or I want to spell check, something.

而只是复制GetSting返回的地址,虽然这个程序表示的名称，我只想做一个拷贝,以便我可以做一个D-A-V-I-D或者F-O-O的版本,大写的或者小写的,或者拼写检查之类的。

So it's an address, it's a pointer, address pointer, synonyms for now, so it's the address of a char so this makes sense because s1 is also the address of a char so if I wanted to make a copy of that address this is absolutely the right syntax.

是一个地址，是一个指针，地址指针，也就是，char型数据的地址,这是有意义的，因为s1也是一个char型数据的地址,所以如果我想要复制那个地址,这个绝对是正确的语法。
