OC 枚举

void test() {
    // 定义一种枚举类型
    enum Season {spring, summer, autumn, winter};
    
    // 定义一个枚举变量s
    enum Season s = winter;
}

void test1() {
    // 定义枚举类型的同时定义一个枚举变量s
    enum Season {spring, summer, autumn, winter} s = spring;
}

    enum {spring = 3, summer, autumn, winter} s = winter;
    
    printf("%d", s);
}
