Basic pointer syntax

Hello, I would just like someone to help clarify some basic pointer syntax, and hopefully this post may be of use to some others also.

Code:

---

#include <cstdio>
#include <cstdlib>
#include <iostream>

using namespace std;

int main(int nNumberofArgs, char* pszArgs[])
{
    int nVar = 37;
    int* pnVar = &nVar;
   
    // the adress of the pointer
    // (where the pointer exists in memory)
    cout << &pnVar << endl;
   
    // the value contained in
    // the variable pointed to (nVar)
    cout << *pnVar << endl;
   
    // the address of the where the variable (nVar)
    // exists in memory
    cout << pnVar << endl;
   
   
   
   
    system("PAUSE");
    return 0;
}

Any comments would be much appreciated! Thanks.

The comments and code agree.
