帮忙！一个菜鸟问题！！！！
枚举的一道题：很简单#include <stdio.h>
void main()
{
enum color{red,yellow,blue,white,black};
enum color i,j,k,pri;
int n=0,loop;
for(i=red;i<=black;i++)
{
for(j=red;j<=black;j++)
if(i!=j)
{
for(k=red;k<=black;k++)
if(i!=k&&j!=k)
{
printf("%-4d",++n);
for(loop=1;loop<4;loop++)
{
switch(loop)
{
case 1:pri=i;break;
case 2:pri=j;break;
case 3:pri=k;break;
}
}
switch(pri)
{
case red:printf("%-8s","red");break;
case yellow:printf("%-8s","yellow");break;
case blue:printf("%-8s","blue");break;
case white:printf("%-8s","white");break;
case black:printf("%-8s","black");break;
}
putchar('\n');
}
}
}
}
错误是：
--------------------Configuration: Cpp1 - Win32 Debug--------------------
Compiling...
Cpp1.cpp
g:\1\cpp1.cpp(7) : error C2676: binary '++' : 'enum main::color' does not define this operator or a conversion to a type acceptable to the predefined operator

执行 cl.exe 时出错.
Cpp1.obj - 1 error(s), 0 warning(s)
我用VC++6-0
