函数名:outtextxy

功 能: 在指定位置显示一字符串

用 法:void far outtextxy(int x, int y, char *textstring);

程序例:

#include <graphics.h>

#include <stdlib.h>

#include <stdio.h>

#include <conio.h>

int main(void)

{

/* request auto detection */

int gdriver = DETECT, gmode, errorcode;

int midx, midy;

/* initialize graphics and local variables */

registerbgidriver(EGAVGA_driver);

initgraph( &gdriver, &gmode, "");

/* read result of initialization */

errorcode = graphresult();

if (errorcode != grOk) /* an error occurred */

{

printf("Graphics error: %s

", grapherrormsg(errorcode));

printf("Press any key to halt:");

getch();

exit(1); /* terminate with an error code */

}

midx = getmaxx() / 2;

midy = getmaxy() / 2;

/* output text at the center of the screen*/

/* Note: the C.P. doesn't get changed.*/

outtextxy(midx, midy, "This is a test.");

/* clean up */

getch();

closegraph();

return 0;
