  • 第1题:

    已知学生记录描述为: struct student { int no; char name[20],sex; struct { int year,month,day; } birth; }; struct student s; 设变量s中的“生日”是“1984年11月12日”,对“birth”正确赋值的程序段是( )。

    A.year=1984;month=11;day=12;

    B.s.year=1984;s.month=11;s.day=12;

    C.birth.year=1984;birth.month=11;birth.day=12;

    D.s.birth.year=1984;s.birth.month=11;s.birth.day=12;


    正确答案:D
    解析:本题考查结构体变量的基本概念。引用结构体成员的方式为:结构体变量名.成员名“.”是“成员运算符”(分量运算符),如果成员本身又是一个结构体类型,则要用若干个成员运算符,一级一级地找到最低一级的成员。只能对最低级的成员进行赋值或存取以及运算,所以选项D)正确。

  • 第2题:

    有以下程序

    #include<stdio.h>

    #include<string.h>

    main( )

    {char str[][20]={“Qne*World”,“one*Dream!”},*P=str[1 ].

    prinff(“%d,”,strlen(p));printf(“%s\n”,P); ’

    }

    程序运行后的输出结果是

    A.9,One*World S)9,One*Dream!

    B.10,One*Dream!

    C.10,One*World


    正确答案:C
    解析:可以将二维数组str看成一个是一个特殊的一维数组,其元素也是一个数组。那么,str[O]为“One*World”,str[1]为“One*Dream!”。
