二级一道题！关于指针、函数、数组

C/C++ code

#include <stdio.h>#include <string.h>void point(char *p){    p++;}main(){    char *p;    char b[4]={'a','b','c','d'};    p=b;    point(p);    printf("%c\n",*p);}

C/C++ code

//================================================================= #include <windows.h>    #include <iostream.h> #include <stdio.h>#include <string.h>void point(char **p){    (*p)++;}main(){    char *p;    char b[4]={'a','b','c','d'};    p=b;    point(&p);    printf("%c\n",*p);}

你的：
void point(char *p)
{
  p++;
}
这里的p虽然移动了，但是p=b;的这个p实际没有发生变化
