    Well since your question is pretty general, my answer will be:

    //to create a regular int variable

    int i;

    //to create a pointer to an int variable

    int *i;

    Notice the *. That's what tells you it's a pointer.

    //using static memory
    int * intPtr = '\0';
    int num = 8;
    intPtr = #
    cout << *intPtr;

    //using dynamic memory
    int * iPtr = new int;
    *iPtr = 5;
    cout << *iPtr;

    Notice that the * operator means pointer when used in declaration and as derefernce operator when used outside of
    declaration and as multiplication operator under other circumstances.
