谁能帮我调通这段经典代码?
函数名: getmaxx
功 能: 返回屏幕的最大x坐标
用 法: int far getmaxx(void);
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;
char xrange[80], yrange[80];
/* initialize graphics and local variables */
initgraph(&gdriver, &gmode, "");
/* read result of initialization */
errorcode = graphresult();
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
exit(1); /* terminate with an error code */
}
midx = getmaxx() / 2;
midy = getmaxy() / 2;
/* convert max resolution values into strings */
sprintf(xrange, "X values range from 0..%d", getmaxx());
sprintf(yrange, "Y values range from 0..%d", getmaxy());
/* display the information */
settextjustify(CENTER_TEXT, CENTER_TEXT);
outtextxy(midx, midy, xrange);
outtextxy(midx, midy+textheight("W"), yrange);
/* clean up */
getch();
closegraph();
return 0;
}
在vc下当然是不行的,在tc下调,编译都没问题,连接时候出现n多undefined symbol:比如 undefined symbol _getmaxx in main.c,undefined symbol _closegraph in main.c;
真郁闷,对tc算是恨之入骨了,大家知道怎么办吗?或者用别的编译器调试?
用borland c怎么调试啊?我这有bc45,调ucosII用的,但不知道怎么调试这个文件...
