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。

It may mean something different and this is sort of just stupid re-use of syntax although frankly it wouldn't really be much fun to have yet a symbol so they went with the same symbol which is pretty reasonable in the context *a of a function prototype this just means *a expect A to be the address of an int and expect B to be the address of an int.

这里的意思有点不同,这是为了重使用的目的,虽然这个符号没有什么意义,所以在函数原型中，他们就使用了相同的符号,这只是表示，期望,是一个int型的地址,期望b是一个int型的地址。
