在解决c 语言中图形系统初始化后还出现BIG Error:Graphics not initialized (use "initgraph") 时DOS窗口

调用图形前加上这个吧
int GraphDriver; /* The Graphics device driver */
int GraphMode; /* The Graphics mode value */
int ErrorCode; /* Reports any graphics errors */
GraphDriver = DETECT; /* Request auto-detection */
initgraph( &GraphDriver, &GraphMode, "" );
ErrorCode = graphresult(); /* Read result of initialization*/
if( ErrorCode != grOk ){ /* Error occured during init */
printf(" Graphics System Error: %s\n", grapherrormsg( ErrorCode ) );
exit( 1 );
}

getpalette( &palette ); /* Read the palette from board */
MaxColors = getmaxcolor() + 1; /* Read maximum number of colors*/
