Problem Description

请定义具有red, orange, yellow, green, blue, violet六种颜色的枚举类型color，根据输入的颜色名称，输出以下六种植物花朵的颜色：
Rose(red), Poppies(orange), Sunflower(yellow), Grass(green), Bluebells(blue), Violets(violet)。如果输入的颜色名称不在枚举类型color中，例如输入purple，请输出I don’t know about the color purple.

Input

输入数据有多行，每行有一个字符串代表颜色名称，颜色名称最多30个字符，直到文件结束为止。

Output

输出对应颜色的植物名称，例如：Bluebells are blue. 如果输入的颜色名称不在枚举类型color中，例如purple, 请输出I don’t know about the color purple.

Sample Input

blue
yellow
purple

Sample Output

Bluebells are blue.
Sunflower are yellow.
I don’t know about the color purple.

Hint

请用枚举类型实现。

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
enum color
{
    red, orange, yellow, green, blue, violet,other
}a;//注意要写上other，以方便下面使用
int main()
{
    char c[31];
    while(gets(c)!=NULL)
    {
        a=other;
        if(strcmp(c,"red")==0)a=red;
        else if(strcmp(c,"orange")==0)a=orange;
        else if(strcmp(c,"yellow")==0)a=yellow;
        else if(strcmp(c,"green")==0)a=green;
        else if(strcmp(c,"blue")==0)a=blue;
        else if(strcmp(c,"violet")==0)a=violet;
        switch(a)
        {
            case 0:printf("Rose are red.\n");break;
            case 1:printf("Poppies are orange.\n");break;
            case 2:printf("Sunflower are yellow.\n");break;
            case 3:printf("Grass are green.\n");break;
            case 4:printf("Bluebells are blue.\n");break;
            case 5:printf("Violets are violet.\n");break;
            default :printf("I don't know about the color %s.\n",c);break;
        }
    }
    return 0;
}
枚举中a是与系统默认序号相对应的
