graphics.h is a very old library for doing graphics in DOS with Borland C++ 3.x.
It's not supported under Windows, and the compiler isn't supported either.

There is a C++ code snippet right here on DaniWeb called "Add a little Graphics to your Console" at:
http://www.daniweb.com/code/snippet173.html

You could potentially draw short lines following the x,y coordinates of your sin(x) function.

Forget about the old graphics.h and Borland BGI DOS stuff, that was left in the 16 bit graveyard a long time ago!

#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <time.h>
#include <string.h>
#include "graphics.h"
#define ESC 0x1b
void main () {
srand(time(NULL));
int GraphDriver=0; GraphMode=0;
initgraph (&GraphDriver ,&GraphMode, "", 640,480);
char tempstring[80];
getch() ;
}
}

Spotted a few errors (although i accept it is work in progress :) ): main should be declared as int main NOT void main....
...GraphMode is undefined as the previous ; finishes the statement (change the previous ; to a , ) and also ESC and tempstring are not used! also do you not have to shut down the driver at the end? - and bear in mind main returns 0; :p

I guess you are using Microsoft VC++...

Sorry may be I made my question not clear....

I just tried to draw y=sin(x) function graph just or something like that y=x+1 or e.t.c.

can you give me some hints for beginning my programm...

for example:

#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <time.h>
#include <string.h>
#include "graphics.h"

#define ESC 0x1b

void main () {

srand(time(NULL));

int GraphDriver=0; GraphMode=0;

initgraph (&GraphDriver ,&GraphMode, "", 640,480);

char tempstring[80];

getch() ;

}

Please do help me with drawing this y = sin(x) graph......

Do forgive me If I make some misunderstanding ....
Thanks

Thanks for suggestion but you know I hardly understand that code and here I am going to show you the code which I began first here and this is only drawing of X and Y oxes and I have to go on drawing sin(x) function please give me your suggestion....

#include "stdafx.h"
#include <graphics.h>
#include <conio.h>


void main()
{


int gd=DETECT, gm;
initgraph(&gd,&gm,"");


int x,y, j=250 ;


setbkcolor(WHITE);
setcolor(LIGHTBLUE);


outtextxy(3,5," I am so stupid hyong I am so stupid sorry sorry !!! "); // output "line" text



x = getmaxx();
y = getmaxy();


x=j;


line(j,0,x,y);


x = getmaxx();
y = getmaxy();


y=j;


line(0,j,x,y);



/*void line(int x0, int y0, int x1, int y1)


{
POINT line[2];
line[0].x = x0;
line[0].y = y0;
line[1].x = x1;
line[1].y = y1;
drawpoly(2, (int*)&line);
}
*/



getch();


closegraph(); // escape graphic mode
}

Thanks very much ....

free_eagle thanks for the link!!!!
I modified the package slightly, and was able to use it with Dev_C++
It works like a charm! I left a little code snippet on DaniWeb showing the details.

thanks again, team work at its best ...

I hope you enjoy your adventures into the world of programming. The logic you learn will help your brain to think better. You are very welcome to ask questions on this forum, most of us are pretty friendly.

Give us enough detail to answer the question. Don't worry too much about the English, it's not my mother language either and I manage to get by.

Here is a one page reference to grpahics.h library with the details of more widely used functions of this library. Also a small program to demonstrate the graphics.
