c++ - 关于指针的这句英文应该怎么解释？

Question

The type of pointer matters not when you have to read the adress,it matters when you dereference or when you perform pointer arithmetic.（The type of pointer play role when you try to dereference or when you try or perform pointer arithmetic.）
能举一个通俗的例子解释下吗？

Answer 1

For a pointer

The
• type is reflected in pointer arithmetic. For example, int *i;i++; i moves 4 bytes at this time. If char *s;s++; the pointer moves 1 byte.
The
• type is also reflected in dereference. For example, the previous *i will read the 4 bytes content starting with the i address, while s will only read the 1 byte content starting with the address s.
