    Or more simply, we can declare the move function inside the class and define it outside the class.
    class Player
    {
    public:
    int x, y;
    float speed;
    void Move(int xa, int ya);
    };
    void Player::Move(int xa, int ya)
    {
    x += xa * speed;
    y += ya * speed;
    }
    int main(void)
    {
    Player player;
    player.x = 1,
    player.y = 2;
    player.speed = 3.4;
    player.Move(1, 2);

    C++ is called C++ because in C "++" was used to increase the value of variable by 1. So if C=1. C++ = 2.
    Which is to say, C++ is an incremented improved version of C.

  • @abx4t
    @abx4t 3 місяці тому

    A side note. If you were to print x or y in the state of the code at 8:03, you would get a completely unknown value.
    This is because, as he talked about in previous videos, when the variable is created it get assigned a memory address.
    We have no idea what previous data was in that memory address, it could be anything.
    Thus, if you print it without initializing it, most often, it will be a seemingly random integer value left over from the last variable (even from another program) that used it.
    As a result, ALWAYS initialize your variables people. ALWAYS.

    Hey Cherno, trying to get back into the programming world, a few questions popped into my head : what do you think about Data Oriented Design (vs. Object Oriented) ?
    How effective can one use and understand DOD vs OOP ? or should i just stick to procedural kind of programming, that is, use C++ only where needed and mostly stick to C ?
    I want to be able to understand the computer and what it is doing for performance reasons. What s the speed difference in those applications between the two designs ?
    there s just not many resources around to poke into.

    I've done many hobby programming projects over the years and yet I've stuck with C and never used object oriented features. However I have seen this and other examples of how it can allow doing the same things I'm doing in a lot less code. I'm doing graphics programming and so an image class makes sense as each image will have its own pixel array and width and height.

    C also has objects these are singular, structures, and arrays. Any of them could hold a pointer to a function and when u call a function through such a pointer that's exactly when things transition into OOP.

    @MrHaggyy Рік тому

    There is one thing that classes do automatically for you that's quite hard and not fully achievable by C. And that's typesafety at compile time. You can typedef structs in C, but you can walk around the typecheck by accident or on purpose. C++ on the otherhand will always give you an compile error if you work with object's of different types, unless you provide a function or overwrite an operator that gives meaning to that combination of types.

  • @choppedsirloin9215
    @choppedsirloin9215 3 роки тому

    This was an awesome explanation! I have done a little bit with UE4 blueprints so it made some things easier to understand, so hopefully the transition to C++ won't be too brutal outside of perhaps the syntax. I have a question though, would there be any reason for someone to want to use a function outside of a class as opposed to nesting it inside a class to make it a method?
    Because from how I'm seeing it, by making it a method, its much easier to use your code and it eliminates the need to have to create reference variables and pass those reference variables around.

  • @chalkchalkson5639
    @chalkchalkson5639 7 років тому +11

    "there is nothing you can do with classes you couldn't do without them" Yeah, C is turing complete and doesn't have classes, but so is assembly or colouring squares on a piece of paper... Just because you could technically do all the same things doesn't mean that anyone on earth is actually capable of doing so :P

    • @FalconGames109

    C# is most certainly not just OO anymore its definitely well seated as a multi-paradigm language and has been for many years. With things like ReactiveX you have data-flow, with LINQ you have functional, both are those are heavily declarative but c# is obviously also heavily imperative, reactive is data driven but async/await sand the TPL is task driven, it has very mature reflection it can easily be written procedurally.
    It is basically the programming language equivalent of what English is to spoken language.
    It takes good ideas, finds really robust implementations and then improves on them.

      If you're learning to code any of these are fine to learn in C++/C#/Python/Java/Javascript in my opinion. I would recommend playing around with a few of them just to get a feel for what you like. I wouldn't worry so much about "learning" the language, as much as learn to code, to start off because a lot of the basics/concepts are very similar. As one progresses it really depends on what is your path / end goal (use the right tool for the job). Each language is a tool, there are pluses and minuses to each. Personally would recommend Python/C#/Javascript to beginners because I think they are the most straight forward and have many branches and uses one can do particularly if you're not sure of your path.
