I am new to Dev C++ and i am creating a program of a game of snake.

In Dev C++ the graphics open in WINDOWS BGI screen whereas the text gets shown in Text console(Dos).
1)i want to know how can i clear the WINDOWS BGI screen ?
2)how can i Close WINDOWS BGI screen so as to return to the text console?

#include<iostream>

#include<graphics.h>
#include<dos.h>
#include<stdlib.h>
#include<stdio.h>
 

using namespace std;
int snake(int);
int main()
{


 
cout<<"WELCOME TO SNAKE WORLD\n PRESENTED BY PRABHJIT,RUHI AND SAURAV OF CS-11";
cout<<"  RULES FOR THE GAME";
cout<<"KEYS---\n w- FORWARD\n a- LEFT TURN\n d- RIGHT TURN\n s- DOWN";
cout<<"  PRESS MOVE(a) KEY TO CONTINUE.....";
cout<<"ENTER YOUR  LEVEL\n";
cout<<"\n1.ROOKIE";
cout<<"\n2.CATCHING UP";
cout<<"\n3.MEDIUM";
cout<<"\n4.MASTER";
cout<<"\n5.THE KING\n";
int choice,prabh;
cin>>choice;
switch(choice)
{
              case 1:prabh=100;
              break;
              case 2:prabh=70;
              break;
              case 3:prabh=50;
              break;
              case 4:prabh=30;
              break;
              case 5:prabh=10;
              break;
              default:cout<<"Wrong option entered...Exiting";
              break;
              }
snake(prabh);              

		      return 0;
              }
int snake(int z)
{int prabh;
prabh=z;
int gdriver = DETECT, gmode, errorcode;
 initgraph(&gdriver, &gmode, "c://tc//");
 cleardevice();
 char ans;
 rand();
 int x=10,y=10,n=1,i;
 int a=0,b=0,x1,y1;
 loop:
 x1=rand()%620;
 y1=rand()%450;
 setbkcolor ( WHITE );
 



 
 again:
 while(!kbhit())
 {
  cleardevice();

              settextstyle(10 , 0 , 2);
  
  outtextxy(x1,y1,"~");
  for(i=1;i<=n;i++)
  {
     if(!kbhit())
   {
    x+=a;y+=b;
    if((x-x1)*(x1-x)>=-25 && (y-y1)*(y1-y)>=-25)
    {n++;goto loop;}

    setcolor ( RED );
    outtextxy(x,y,"");
    delay(prabh);
   }
   else
   {goto loop1;}
  }
 }
 loop1:
 ans=getch();
 if(ans=='w'||ans=='W' && b<=1 && b!=5)
 {a=0;b=-5;}
 if(ans=='s'||ans=='S' && b<=460 && b!=-5)
 {a=0;b=5;}
 if(ans=='a'||ans=='A' && a<=1 && a!=5)
 {a=-5;b=0;}
 if(ans=='d'||ans=='D' && a<=630 && a!=-5)
 {a=5;b=0;}
 if(ans=='q'||ans=='Q')
 {cout<<"GAME ABORTED";}
 if((x<0)|(y<0)|(x>640)|(y>480)) 
{cout<<"GAME ABORTED";        /* over here i want to write the code that can close the Windows BGI screen and return me to text console*/

}
 goto again;
 return 0;
  
}

#1: repaint the entire screen in the same color. Something like this:

RECT rect;
    HBRUSH hBrush;
<snip>
    case WM_PAINT:
        hdc = BeginPaint(hWnd, &ps);
        GetWindowRect(hWnd,&rect);
        hBrush = CreateSolidBrush(RGB(255,0,0));
        SelectObject(hdc,hBrush);
        FillRect(hdc, &rect, hBrush);
        EndPaint(hWnd, &ps);
        DeleteObject(hBrush);
        break;

#2: I know of no way to do that. The program is created for either text or windows, the two can not be mixed in the same program.

AS U CAN SEE IN MY PROGRAMME first the text console opens and only after i enter a no according to difficulty level THE WINDOWS BGI screen opens.

NOW,the thing is i want the WINDOWS BGI SCREEn to terminate as soon as Snake crosses the windows border or the x,y position i give in the coding.Do u know any way of that

>> AS U CAN SEE IN MY PROGRAMME ...
Please don't SHOUT, thank you.

As for the problem, I believe closegraph() will do what you want.

I did't realize Dev-C++ could generate 16-bit code like Turbo C. dos.h is not supported with 32-bit compilers.

thanks for this code and i found my problem's solution in this code. got ride of the frustration. thank a lot for you ....
