I have a problem with Turbo C because I am trying make to following program
work with a Hercules graphics card :
/* filename : X-J29.C
purpose : having fun with Turbo C Graphics Library (screen saver)
requires CGA/EGA/VGA*/
/* include header files */
#include <graphics.h>
#include <stdlib.h>
#include <conio.h>
#include <stdio.h>
main()
{
{
/* code to detect graphic adapter */
int graphmode, graphdriver = DETECT;
int color;
int i, j, x, y;
struct viewporttype vp;
int height, width;
int maxcolors;
struct palettetype palette;
if (registerbgidriver(Herc_driver) < 0) exit(1);
if (registerbgidriver(EGAVGA_driver) < 0) exit(1);
if (registerbgidriver(CGA_driver) < 0) exit(1);
initgraph(&graphdriver, &graphmode, "");
graphdefaults();
maxcolors = getmaxcolor() + 1;
getviewsettings( &vp );
width = (vp.right - vp.left) / 15; /* get width of the box
*/
height = (vp.bottom - vp.top) / 10; /* Get the height of the box
*/
x = y = 0; /* Start in upper corner
*/
color = 1; /* Begin at 1st color
*/
for( j=0 ; j<10 ; ++j ){ /* For 10 rows of boxes
*/
for( i=0 ; i<15 ; ++i ){ /* For 15 columns of boxes
*/
setfillstyle( SOLID_FILL, color++ ); /* Set the color of box
*/
bar( x, y, x+width, y+height ); /* Draw the box
*/
x += width + 1; /* Advance to next col
*/
color = 1 + (color % (maxcolors - 2)); /* Set new color
*/
} /* End of COLUMN loop */
x = 0; /* Goto 1st column */
y += height + 1; /* Goto next row */
} /* End of ROW loop
*/
while( !kbhit() ){ /* Until user enters a key...
*/
setpalette( 1+random(maxcolors - 2), random( 65 ) );
}
setallpalette( &palette );
getche();
closegraph();
return;
}
} /* End of program */
