我用turboc2.0/3.0都试过为什么编译不过去

#include&nbsp;&ltgraphics.h&gt&nbsp;<br />#include&nbsp;&ltstdlib.h&gt&nbsp;<br />#include&nbsp;&ltstdio.h&gt&nbsp;<br />#include&nbsp;&ltconio.h&gt&nbsp;<br /><br />int&nbsp;main(void)&nbsp;<br />{&nbsp;<br />/*&nbsp;request&nbsp;auto&nbsp;detection&nbsp;*/&nbsp;<br />int&nbsp;gdriver&nbsp;=&nbsp;DETECT,&nbsp;gmode,&nbsp;errorcode;&nbsp;<br />int&nbsp;midx,&nbsp;midy;&nbsp;<br />int&nbsp;stangle&nbsp;=&nbsp;45,&nbsp;endangle&nbsp;=&nbsp;135;&nbsp;<br />int&nbsp;radius&nbsp;=&nbsp;100;&nbsp;<br /><br />/*&nbsp;initialize&nbsp;graphics&nbsp;and&nbsp;local&nbsp;variables&nbsp;*/&nbsp;<br />initgraph(&gdriver,&nbsp;&gmode,&nbsp;&quot;&quot;);&nbsp;<br /><br />/*&nbsp;read&nbsp;result&nbsp;of&nbsp;initialization&nbsp;*/&nbsp;<br />errorcode&nbsp;=&nbsp;graphresult();&nbsp;/*&nbsp;an&nbsp;error&nbsp;occurred&nbsp;*/&nbsp;<br />if&nbsp;(errorcode&nbsp;!=&nbsp;grOk)&nbsp;<br />{&nbsp;<br />printf(&quot;Graphics&nbsp;error:&nbsp;%s

首先要确保编译环境的参数设置正确了<br /><br />另外需要把“EGAVGA.BGI”文件，拷贝到相应.exe的生成目录下
