比较常量

Question

假设我有以下常量:

const char EASY = 'E';
const char NORMAL = 'N';
const char HARD = 'H';
const char LUNATIC = 'L';

我希望 LUNATIC 大于 HARD，后者大于 NORMAL，后者大于 EASY。

我如何定义它们，使其适用于以下内容:

int main(){
    char diff1 = LUNATIC;
    char diff2 = NORMAL;

    if (diff1 > diff2){
        printf("Lunatic is harder than normal");
    }
    return 0;
}

Answer 1

使用枚举:

enum Difficulty
{
    EASY,
    NORMAL,
    HARD,
    LUNATIC
};

int main(){
    char diff1 = LUNATIC;
    char diff2 = NORMAL;

    if (diff1 > diff2){
        printf("Lunatic is harder than normal");
    }
    return 0;
}
