window creating w/ textbackground help

#include<stdio.h>
#include<conio.h>

main()
{
window(10,55,22,77);
textbackground(RED);
clrscr();
}

is this correct?? i run it but it didn't display anything. my prof. have an example bout this he said that the #'s inside the parentheses are the sizes of the box, (x1,y1,x2,y2) x1 is the top line of the box, y1 is left line of the box,x2 is the bottom line of the box, and y2 is the ryt line but how??

Maybe try this:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>

int main()
{
     window(100, 50, 360, 350);
     textbackground(RED);

     _sleep(5000);

     clrscr();
     return(0);
}

And you do know how a grid works, and how to find the x,y coordinates right?

edit:
Oh, yeah! You have to use the BB-code tags(it's the law):
