    My first game

    It's just a text based version of Connect Four. I ran into that old Connect Four tournament thread and that inspired me to write my own version. It pretty much sucks (it is the first full game I've written in any language). Feel free to offer constructive criticism (or non-constructive, whichever). It's only two player right now as I would have no idea where to start with programming the AI. The source code is attached below. Just copy and paste it into your compiler (for I do not have win zip to upload a zip file).

    I've heard the Min-Max algo is suitable for connect four clones.
    I googled up this .pdf file

    not bad but after the iostream header you should put
    [code]
    using std::cout;
    using std::cin;

    my compiler says this error:
    g++ -g run.x connectfour.cpp && ./run.x
    connectfour.cpp: In function `int main()':
    connectfour.cpp:29: implicit declaration of function `int system(...)'


    I am on linux so that could aslo be the reason

    I always use 'using namespace std;'. I just don't see why someone would waste time writing 'std::cout', etc.

    And yes, I think system(...) is a Windows thing.

    system() itself is a standard function. However the program name you put in it may not be.

    kleid thats a good guess considering its C++ code (#include <iostream> is a dead give away)

    I always use 'using namespace std;'. I just don't see why someone would waste time writing 'std::cout', etc.
    This has been discussed in circles many times. I'd suggest you do a board search to find the pros & cons of it. Its much more then having to type std::

    You might as well go like this:
    Code:
    #define cout std::cout
    cout << "Much better *sips a glass of wine*";

    Oh god no. I'd rather someone use "using namespace std;" all the time then use a macro

    Yes, this is C++ code (sorry I didn't mention that earlier).

    Btw, is there really a difference between using 'using namespace std;' and using 'std::cout'?

    Code:
    using namespace std;
    brings the entire std namespace into the global namespace
    Code:
    using std::cout;
    brings only std::cout into the global namespace

    whats wrong with the macro?
    A lot. Here are two code segments that would not work with the above macro:
    Code:
    std::cout<<"Hello world"<<std::endl;
    mynamespace::<<cout<<"Hello world"<<mynamespace::endl;

    You'd also get problems if you ever used cout in a string... though I wonder how likely that is to happen...
