    Need a quick example! Operator overloading and matrix

    So i have a matrix that is [2][2], and i want to be able to have:
    [cody]
    Matrix a(1, 2, 3, 4); //a = [2][2] - 1, 2, 3, 4
    Matrix b(4, 3, 2, 1; //b = [2][2] - 4, 3, 2, 1
    Matrix c;

    c = a + b;
    [/code]

    I have (summed up):
    Code:
    class Matrix
    {
    public:
        Matrix();
        Matrix(double a, double b, double c, double d);
        Matrix operator + (Matrix first);
    private:
        //the matrix, etc
    };
    
    Matrix::Matrix operator + (Matrix& a)
    {
    
    
    }

    I don't know how to implement it, no tutorial i can find explains it well enough to me. I don't see how i can only pass one object and what to return....

    What it needs to do is:
    Code:
    | 1  2  |        | 4  3 |         | 5   5 |
                   +                = 
    | 3  4  |         |2   1|          |5   5 |

    Can anyone help me out quick? Thanks.

    >>(summed up)<<

    post the whole thing...we need to see how you handled the overloaded "+"

    Don't re-post a question that has been answered and you either haven't looked or haven't bothered asking for further details on. If you still want the question answered, go back to your old thread and say "I still don't get it, can someone explain (some part that you're having trouble on) better?".
    Just Google It. √
