thinking: buf and p is exactly equivalent to it?
buf: array name is a pointer, the first element of the array address, but [it] is a read-only constants;
as defined in the first address and length of the stack, the latter system is conducive to recycling
understanding * (buf + 1); // ok here as a fixed value buf operation
