The pointer to a data member is a mysterious and useful language feature, especially if you need to investigate the underlying layout of class members in detail. This investigation can be used to determine whether the vptr is placed at the beginning

1. char * Char * buff = "orisun "; Sizeof (buff) = 4 store a pointer with 32 bits Strlen (buff) = 6 strlen returns the actual length of the string, excluding '\ 0' at the end' 2. Char [N] Char Bu [100] = "orisun"; From 7th to 100th bits are both '\ 0

The reason why the char * string is discarded and the string class in the C ++ standard library is used is because it is compared with the former, and does not have to worry about whether the memory is sufficient, the string length, and so on. It

(1) The reference must be initialized at the same time (the pointer can be initialized at any time). Pointers and references look completely different (pointers use operators '*' and '->', and references use operators '.'), but they seem to have the
