HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
void setFontSize(int a,int b)
{
     testFont[0] = a;
	 testFont[1] = b;
	 SetCurrentConsoleFontEx(hConsole, TRUE, testFont);
}
   void size_convertor(int sk=0){

    switch(sk){
    case 1:
        setFontSize(2,2);
        break;
    case 2:
        setFontSize(4,4);

Answer: Don’t do that.

Font size is the user’s purview. Not the program’s.

If you want specialized font stuff, create your own window and select a font into the GDC and draw with that.

OR, create a shortcut for your program and set the font with that.

Sorry it isn’t the answer you wanted.

The problem is, the only connection between the console is a data stream of what text goes into and out of the console. The console is a separate program that is the mouth piece of you program. The issue comes when different operating systems/flavors use different consoles. There is no common "settings" channel between your program and the console program, only the text streams.

--Edit--

I forgot to mention there is a "common language" that most consoles use (excluding windows because they are special). These are ANSI escape code, which can be used to change color and cursor position. I usually don't like referencing Wikipedia but this page is very good starting point. These codes are sent over the data stream already established.

If you are going to do modal programming with the console, use NCurses on *nixen and the Windows API + windows VT escape sequences on Windows. (This is what “most” programs will do.)

You need to include windows.h and the User32 library.

[kryganas]

how import User32 library,
i using codeblock
