这个函数可以通过

void changetextcolor()

{

switch (gettextcolor()){

case WHITE:settextcolor(RED); break;

case RED:settextcolor(LIGHTRED);

case LIGHTRED:settextcolor(YELLOW); break;

case YELLOW:settextcolor(GREEN); break;

case GREEN:settextcolor(CYAN); break;

case CYAN:settextcolor(BLUE); break;

case BLUE:settextcolor(MAGENTA); break;

case MAGENTA:settextcolor(WHITE); break;

default:settextcolor(WHITE); break;

}

}

这个函数提示错误

void changelinestyle(){

switch (getlinestyle())

{

case PS_SOLID:

default:

break;

}

}

哪位大神给详细讲讲
