//Changing the font styles using a loop.

settextstyle(GOTHIC_FONT,HORIZ_DIR,5);
/*The above statement means that it is the default font in the horizontal

//Outputting a message.
outtextxy(200,200,"Gothic font");
getch();
cleardevice();
settextstyle(SMALL_FONT,VERT_DIR,5);
/*The above statement means that it is the small font in the vertical
direction and the font size is 5.*/
//Outputting a message.
outtextxy(200,200,"Small font");
getch();
cleardevice();
settextstyle(SANS_SERIF_FONT,HORIZ_DIR,5);
/*The above statement means that it is the sans serif font in the horizontal
direction and the font size is 5.*/
//Outputting a message.
outtextxy(200,200,"Sans Serif font");
getch();
closegraph();
}

This graphics program switches between default font, triplex font, gothic font, small font and sans serif font using the 'settextstyle' command.
