how to get the right position of showing entered value?
Please run this program, you will se the problem with the position of the value that you enter.
I dont know how to fix it :(
Help me plz.

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

int main(void)
{
   /* request auto detection */
   int gdriver = DETECT, gmode, errorcode;

   /* initialize graphics and local variables */
   initgraph(&gdriver, &gmode, "");

   /* read result of initialization */
   errorcode = graphresult();
   if (errorcode != grOk)  /* an error occurred */
   {
      printf("Graphics error: %s\n", grapherrormsg(errorcode));
      printf("Press any key to halt:");
      getch();
      exit(1); /* terminate with an error code */
   }

   int a;

   outtextxy(100,50,"enter number: "); //
   gotoxy(100,70);
   cin >> a;           //I want this value to be shown in a right place
                       //for example:
                       //enter number: 1111


   /* clean up */
   getch();
   closegraph();
   return 0;
}

I don't use DOS, so I can't help you, I only noticed one thing...

What exactly is it doing? I can't compile your program because you use borland graphics library which I don't have. What mode are you in? Is it 80x25 16 color text mode?

gotoxy() is for the DOS-prompt, so it will only accept values up to (80, 25).

You can mix cin with the BGI graphics but it won't be pretty.
Best way is to use getch() and then echo the typed char back to the screen using outtextxy(). Something like this:

char numberStr[20];
outtextxy(some_x, some_y, "Enter number:"); 
do
{
  numberStr[i]=getch();
  numberStr[i+1]='\0';
  outtextxy(some_x + offset + something*i, some_y, &numberStr[i]);
}while(isdigit(numberStr[i++]));

numberStr[i]='\0';

You will need to add error handling: check "i" so that the buffer numberStr doesn't overflow etc etc.

My program is correctly working now
Thanh all :)
