    printf("2.9  %d\n", *&myarray); // outputs a memory address

    printf("3.   %d\n", *(a_goddamn_pointer + 1)); // points to 2nd element of array (outputs '4')

    printf("4.   %d\n", *a_goddamn_pointer + 1); // adds 1 to 1st element of array (outputs '101')

    printf("5.   %s\n", &myarray[2]); // outputs 3rd elem of array ('c').  
    //Note: kind of surprising that this works!

    printf("5.5  %p\n", &myarray[2]); // outputs a pointer memory address!  
    //MORAL: keep an eye on format identifiers!

    // printf("6.   %s\n", myarray[2]); // This will throw a segfault!

    // printf("6.5   %s\n", *myarray[2]); // Segfault

    // printf("7.   %s\n", *&myarray[2]);  // Segfault

    printf("7.   %s\n", myarray);  // outputs 'd'

    printf("8.   %s\n", &myarray[4]);  // outputs 'e'

    printf("9.   %s\n", myarray);  // outputs 'd'

    x = &a_goddamn_pointer; // throws a warning (x is not a pointer)
    y = a_goddamn_pointer; //  throws a warning (y is not a pointer either)
    z = *a_goddamn_pointer; // is fine - z will equal 0

    return 0;
