    **argv

    I've noticed when reading through some winAPI tutorials. May I ask why there's two * instead of just one?

    Calling function from its memory address?

    I searched the internet for a method of doing this, and came across this neat little trick:



    typedef void func(void);
    func* f = (func*)0xdeadbeef;
    f();


    And I'm a little stuck here on...

    Why can't I do the second method?

    Working method:



    sf::Vector2i *position = &sf::Mouse::getPosition();
    gui.didClickButton(position);

    Now, that works just fine. But, why can't I just do:

    However, does this act just like a pointer? It's just not technically labeled as one?..

    Yes, g is the object. It can be named whatever, so long as you refer to that same object name throughout the code.

    e.g:

    However, may I ask why you moved the address symbol (&)? (from the return statement to the function type information)

    printf("3 %c", (isEven(4)) ? 'Y' : 'N');

    I'm using that to test the function:



    int isEven(int x){
    return !(x%2);
    }
  24. More efficient way to structure this function?

    I have the very basic function below:



    int isEven(int x){
    return ((x%2) == 0) ? 1 : 0;
    }
