Question
Sir,I am using Turbo c++. While running the graphics programs I am getting BGI error as "graphics not initialized(use initgraph)". How can I solve this problem sir.
this is my code for your reference....

#include<iostream.h>
#include<graphics.h>
#include<math.h>
#include<conio.h>
#include<dos.h>

void main()
{
clrscr();

int gd=0,gm=0,xmin=0,xmax=604,ymin=0,ymax=478;
float i,j,a=302,b=239;




  initgraph(&gd,&gm,"..//bgi");


 for(i=1;i<=10;i++)
{ settextstyle(SANS_SERIF_FONT, HORIZ_DIR, i);
 outtextxy(270,150,"S");
 delay(300);
 }

 closegraph();
 clrscr();

initgraph(&gd,&gm,"..//bgi");

  for(i=1;i<=10;i++)
{ settextstyle(SANS_SERIF_FONT, HORIZ_DIR, i);
 outtextxy(270,150,"T");
 delay(300);
 }

 closegraph();
 clrscr();

 initgraph(&gd,&gm,"..//bgi");

 for(i=1;i<=10;i++)
{ settextstyle(SANS_SERIF_FONT, HORIZ_DIR, i);
 outtextxy(270,150,"O");
 delay(300);
 }

 closegraph();
 clrscr();

  initgraph(&gd,&gm,"..//bgi");

  for(i=1;i<=10;i++)
{ settextstyle(SANS_SERIF_FONT, HORIZ_DIR, i);
 outtextxy(270,150,"P");
 delay(300);
 }

 closegraph();
 clrscr();

  initgraph(&gd,&gm,"..//bgi");

  for(i=1;i<=10;i++)
{ settextstyle(SANS_SERIF_FONT, HORIZ_DIR, i);
 outtextxy(270,150,"I");

 }


 closegraph();
 clrscr();

  initgraph(&gd,&gm,"..//bgi");

  settextstyle(TRIPLEX_FONT, HORIZ_DIR, 5);
  outtextxy(100,150,"!!  S T O P   I T  !!");






          //302,239 is the origin    j-239
getch();
closegraph();
}

Answer
Perhaps you are not calling initgraph correctly.

initgraph(&gd,&gm,"..//bgi");

The // indicates a start of comment in C++

You should use just 1 slash "../bgi"

You need a double slash when you specify a file like this "..\\bgi"

The double slash "\\" is necessary because the single slash "\" is an escape character in C/C++.


If that is not the issue, then I cannot help you further because I don't have access to Turbo C++ and I don't know anything about the Turbo graphics.

Best regards
