  • 第1题:

    以下对枚举类型名的定义中正确的是______。

    A.enum a={one, two,three};

    B.enum a{one=9,two=1,three};

    C.enum a={"one","two","three"};

    D.enum a{"one", "two","three"};


    正确答案:B
    解析:声明枚举类型用enum开头。例如:enumweekday(sun,mon,tue,wed,thu,fri,sat);说明:1、在C编译中,对枚举元素按常量处理,同时可以改变他们的值。2、枚举值可以用来做判断比较。3、一个整数不能直接赋给一个枚举变量。
