    int a; // a is an integer 
    int *aPtr; // aPtr is an int * which is a pointer to an integer 

    a = 7; // assigned 7 to a 
    aPtr = &a; // assign the address of a to aPtr 

    cout << "The address of a is " << &a << "\nThe value of aPtr is " << aPtr; 
    cout << "\n\nThe value of a is " << a << "\nThe value of *aPtr is " << *aPtr; 
    cout << "\n\nShowing that * and & are inverses of " << "each other.\n&*aPtr = " << &*aPtr << "\n*&aPtr = " << *&aPtr << endl;
