    类MyClas的定义如下： class MyClas{ public: MyClas(){} MyClas(int a){ value=new.int(i); } int *value; }; 若要对类中的value赋值，则下面的语句中正确的是( )

    A．MyClas x;x.value=10;

    B．MyClas x; *x.value=10;

    C．MyClas x;x. *value=10;

    D．MyClas x(10);


    正确答案：D
    解析：选项A中，直接对地址赋值，因此选项A是错误的；c++中不能对未初始化的指针变量赋值，因此选项B是错误的；选项C有语法错误；选项D通过调用类的构造函数给value赋初值10。

    B

    3

    C

    5

    D

    6

    E

    8


    正确答案： D
    解析：
    根据题干Ωn =n2 /3-n=s. n为正整数，且s为正整数；根据函数可知只有当n是3的倍数时，s才能为整数，否则如果n2 /3不是整数，s也不是整数。现在可以从符合条件的n的最小值3代入到函数中。当n=3时，n2 /3-n =32 /3-3 = 3-3 = 0 = s；当n=6时，n2 /3-n = 62 /3-6 = 12-6 = 6 = s。所以故选D。
