Graphical functions in C

Question

Why I see nothing when I run my code ? I use DOSBox.

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <dos.h>
#include <conio.h>
#include <bios.h>
#include <ctype.h>
#include <math.h>

int main() {
    int gdriver = DETECT,gmode = 0;
    initgraph(&gdriver,&gmode,"C:\\TC\\BGI");
    struct time t;
    moveto(5,10);
    outtext("Hello");
    moveto(6,11);
    outtext("World**strong text**");
    moveto(1,24);
    outtext("Press: 1-About_Author, 2-Current_Time,ESC to EXIT");
    closegraph();
    return 0;
}

Check the result with `graphresult()`. It was always a pain to make Turbo C understand where its own libraries were located. IIRC you could solve such problems by adding "egavga.bgi" to your project. — Lundin, Dec 11 '15 at 09:05
I have changed int gdriver = 9,gmode = 0; 9 - VGA, 0 - VGA but, output is empty :( — Denys Shabelnyk, Dec 11 '15 at 09:22
It is not an include file, it is a binary. Try adding it to your project through Project -> Add item. — Lundin, Dec 11 '15 at 09:22
I have done it, but when I am compiling files I am catching more errors in "egavga.bgi". Any ideas ? — Denys Shabelnyk, Dec 11 '15 at 12:21
Dropping the DOS junk in favour of a modern graphics library sounds like the most feasible solution. — Lundin, Dec 11 '15 at 12:28
Thank's for your good advice. I will use WinBGIm from https://www.cs.colorado.edu/~main/bgi/dev-c++/ — Denys Shabelnyk, Dec 11 '15 at 14:29
That's not modern though... Dev C++ is in fact no longer maintained. I was rather thinking about things like OpenGL, DirectX, QT, etc etc. — Lundin, Dec 11 '15 at 14:39

Your code is right. The problem is with the path you are giving to search for the display driver files "C:\\TC\\BGI". This generally happen because the tc is not root of the mounted drive or the .exe file path you are using is not c:\\TC. Replace the path with "..//bgi". This will redirect from bin(the current working directory) to bgi.
