遇到点问题，怎么修改
#include"stdio.h"
enum COLORS {BLACK,BLUE,GREEN,CYAN,RED,MAGENTA,BROWN,LIGHTGRAY,LIGHTGRAY,LIGHTBLUE,LIGHTGREEN,LIGHTCYAN,LIGHTCYAN,LIGHTMAGENTA,YELLOW,WHITE};
void main()
{ enum COLORS a,b,c;
enum COLORS *pa;
int d=-2;
a=RED;
b=WHITE;
printf("\na=%d b=%d c=%d d=%d",a,b);
c=a+b;
if(a>b) pa=&a;
else pa=&b;
*pa=d;
printf("\na=%d b=%d c=%d d=%d",a,b,c,d);
}

[解决办法]
D:\VC语言\helloc\helloc.cpp(2) : error C2086: 'LIGHTGRAY' : redefinition
这个是说变量重定义了，你是不是之前定义过，或者是系统已定义

这个说你定义的变量不能转为int
