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;  
}
