c++获取枚举值的名称

#include <iostream>

#define STRINGIFY_ENUM(e) #e

enum Color {
    RED,
    GREEN,
    BLUE
};

const char* colorToString(Color color) {
    switch (color) {
        case RED:   return STRINGIFY_ENUM(RED);
        case GREEN: return STRINGIFY_ENUM(GREEN);
        case BLUE:  return STRINGIFY_ENUM(BLUE);
        default:    return "Unknown Color";
    }
}

int main() {
    Color color = RED;

    std::cout << "Enum Name: " << colorToString(color) << std::endl;

    return 0;
}
