    Syntax Trouble

    I am having second thoughts about the book I am studying.. on more than one occasion, I have ended up debugging the author's examples... (Windows Programming with C++ -Henning Hansen) Here is my latest example:

    Code:
    LRESULT CALLBACK WndProc(HWND hWindow, UINT msg, WPARAM wParam, LPARAM lParam)
    {
            
    
        static BYTE Pixel[6][5] = {0, 255, 0, 255, 0,  0, 
                                   255, 0, 255, 0 255, 0, 
                                   0, 255, 0, 255, 0,  0,
                                   255, 0, 255, 0, 255,0,
                                   0, 255, 0, 255, 0,  0};
    
    
        static HBITMAP hBitmap;
        static HDC hdcmem;
    
        switch(msg)
        {
    
            case WM_LBUTTONDOWN:
    The program compiles except for one error.. stating that Pixel data structure was terminated incorrectly..

    This method for initializing a 2D array looks kinda shady to me..

    Q: is there a better/preferred method for initializing a 2D array like the one above..??

    thanks in advance

    Code:
    static BYTE Pixel[6][5] = {0, 255, 0, 255, 0,  0, 
                                   255, 0, 255, 0, 255, 0, 
                                   0, 255, 0, 255, 0,  0,
                                   255, 0, 255, 0, 255,0,
                                   0, 255, 0, 255, 0,  0};
    Looks like you missed a comma.

    Each dimension needs it's own set of braces
    Code:
        static BYTE Pixel[6][5] = { {0, 255, 0, 255, 0,  0}, 
                                   { 255, 0, 255, 0 255, 0 }, 
                                   { 0, 255, 0, 255, 0,  0 },
                                   { 255, 0, 255, 0, 255,0 },
                                   { 0, 255, 0, 255, 0,  0 }};
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
