最简单的问题 枚举 类型数据使用问题

[slwang2003]

如题 我用

enum color{red,yellow,blue,white,black};
enum color i;


for (i=red;i<=black;i++)

{
printf("%d\n",i);
}
但是到for (i=red;i<=black;i++)时出现
binary '++' : 'enum main::color' does not define this operator or a conversion to a type acceptable to the predefined operator错误请问如何解决

谢谢

i++改为
(int(i))++

[slwang2003]

i++改为
(int(i))++
后出现'++' needs l-value的错误

[handwolf]

for (i=red;i<=black;i = i+1)

[slwang2003]

i++改为
for (i=red;i<=black;i = i+1)
后出现'
'=' : cannot convert from 'int' to 'enum main::color'的错误

[handwolf]

enum color{red,yellow,blue,white,black};
enum color i;


for (i=red;i<=black;i = (color)((int)i+1))
{
printf("%d\n",(int)i);
}

就是类型的转换问题，上面是强迫转换
