程式例
#include<graphics.h>#include<stdlib.h>#include<string.h>#include<stdio.h>#include<conio.h>int main(void){/*request auto detection*/intgdriver=DETECT,gmode,errorcode;intbkcolor,midx,midy;char bkname[35];/*initialize graphics and local variables*/initgraph(&gdriver,&gmode,"");/*read result of initialization*/errorcode=graphresult();/*an error occurred*/if(errorcode!=grOk){printf("Graphicserror:%s\n",grapherrormsg(errorcode));printf("Press anykey to halt:");getch();/*terminate with an error code*/exit(1);}midx=getmaxx()/2;midy=getmaxy()/2;setcolor(getmaxcolor());/*for centering text on the display*/settextjustify(CENTER_TEXT,CENTER_TEXT);/*get the current background color*/bkcolor=getbkcolor();/*convert color value into a string*/itoa(bkcolor,bkname,10);strcat(bkname,"is the current background color.");/*display a message*/outtextxy(midx,midy,bkname);/*clean up*/getch();closegraph();return0;}重編者 註：itoa(bkcolor,bkname,10); 並沒有使顏色值轉換成字元串。運行結果顯示：0 is the current background color.
