    {

    i need an explanation about the syntax of this:
    Code:
    void color(int colorNum)
    {
             //colors
             HANDLE  hConsole; 
             hConsole = GetStdHandle(STD_OUTPUT_HANDLE); 
             SetConsoleTextAttribute(hConsole, colorNum);
             //colors
    }
    
    void gotoxy(int x, int y)
    {
    COORD coord;
    coord.X = x;
    coord.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
    }
    why is it in that format?
    thanks

    HANDLE is something like pointer to "something", here the console.
    COORD is a struct with a "x" and a "y" member.

    What do you mean by format? Its indentation?

    i mean how it is contruct.

    void color(int colorNum)
    {
    //colors
    HANDLE hConsole;
    hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hConsole, colorNum);
    //colors
    }

    for example:
    why is it (hConsole = GetStdHandle(STD_OUTPUT_HANDLE)
    is declared as this.
    i mean i want to know what is the required format for color and for goto function.

    You figure it out by reading about each function on MSDN. They're all Win32 API calls.
    GetStdHandle Function (Windows)
    SetConsoleTextAttribute Function (Windows)
    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.
