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?

对于一个指针
int *i;i++;
此时i移动了4 bytes,若是char *s;s++;
指针移动 1 byte.*i
会读取以i
地址开头的4 bytes内容,而s
则只读取s
为首地址的的1 byte内容.
