C + + pointer change value

1. #include <iostream>

using namespace Std;

void Move (int *p) ====>void Move (*&p)
{

p++;
}

int main ()
{
int attr[]={1,2,3,4,5};
int *p=attr;
cout<<*p<<endl;
p++;
Move (p);
cout<<*p<<endl;
return 0;
}


Why the second print value does not change, the pointer is also a variable, the pointer is can change the value, but you here: Change the pointer value (address), did not change the value of the pointer to move (*&AMP;P) can be broken 2.c language written in this #include <stdio.h>
void Move (int* p)
{

++p; =======> (*p) + +;
printf ("%d \ n", *p);
}

int main ()
{
int attr[]={1,2,3,4,5};
int *p=attr;
printf ("%d \ n", *p);
p++;
Move (p);
printf ("%d \ n", *p);
return 0;
} in this case.
