#include<graphics.h>
#include<stdlib.h>
#include<stdio.h>
#include<conio.h>
int main(void)
{   clrscr();
    int gdriver = DETECT,gmode,errorcode;
    int midx,midy;
    initgraph(&gdriver,&gmode,"");
    errorcode=graphresult();
    if(errorcode != grOk)
    {   //cout<<"Eroor"<<grapherrormsg(errorcode);
    getch();
    exit(1);
    }
    midx=getmaxx()/2;
    midy=getmaxy()/2;
    moveto(midx,midy);
    outtext("Pallob");
    outtext("Suba");
    getch();
    closegraph();
    return 0;
}
