    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.
