#include <iostream>
#include <typeinfo>

enum Color

	COLOR_SKYBLUE
};

int main() {
	using namespace std;
	printf("%d\n", COLOR_BLACK); //0
    Color my_color = static_cast<Color>(3);
}

 

2. enum class

#include <iostream>


int main() {

	using namespace std;
	enum class Color {
		RED,
		BLUE
	};

	enum class Fruit {
