当然：

#include <iostream>  
  
// 定义一个枚举类型  
enum class Color {  
    RED, GREEN, BLUE  
};  
  
// 函数返回枚举类型  
Color getRandomColor() {  
    static int nextColorIndex = 0;  
    Color color = Color(nextColorIndex);  
    ++nextColorIndex;  
    if (nextColorIndex > 2) nextColorIndex = 0; // 循环使用颜色值  
    return color;  
}  
  
int main() {  
    for (int i = 0; i < 5; ++i) {  
        Color randomColor = getRandomColor();  
        std::cout << "Random color: " << static_cast<int>(randomColor) << std::endl;  
    }  
    return 0;  
}
