C++ - These mysteryous pointers

Question

Why doesn't *y++ increment x?
#include <iostream>
using namespace std;
int main() {
int x, *y;
x = 5;
y = &x;
*y++;
cout << x << endl;
x--;
cout << x;
return 0;
}

Answer 1

~ swim ~ yes i realised it, its pointing to another address. Indeed.

Answer 2

A pointer is a memory address that contains a value. If you increment a pointer, you go to the next address position. It does not increment the value contained in the pointer

Answer 3

Yes, you can do ++*y; or, *y=*y+1; or (*y)++;
Seems that pointers need first increment and then assignment. In second case *y=*y+1; all second part (*y+1) is assigned to *y. In case *y++; i suppose that first *y =*y and then +1 which is lost. I think its like typing *y+1; with no assignment or you just do this *(y+1) which is just another menory address.
And thats why i hate pointers. :D
