  • 第1题:

    使用VC6打开考生文件夹下的工程proj2。此工程包含一个源程序文件main2.cpp,但该程序运行有问题。请改正main函数中的错误。

    源程序文件main2.cpp清单如下:

    //main2.cpp

    include <iostream>

    using namespace std;

    class MyClass

    {

    public:

    MyClass(int m)

    {

    member=m;

    }

    ~MyClass() {}

    int GetMember()

    {

    return member;

    }

    private:

    int member;

    };

    MyClass MakeObject(int m)

    {

    MyClass *pMyClass=new MyClass(m);

    return *pMyClass;

    }

    int main ( )

    {

    int x=7;

    /************found**************/

    MyClass *myObj=MakeObject(x);

    /*************found*************/

    cout<<"My object has member"<<myObj.GetMember()<<end1;

    return 0;

    }


    正确答案:修改后的主函数为: int main() { int x=7; MyClass *myObj=&MakeObject(x); cout"My object has member"myObj->GetMember()end1; return 0; }
    修改后的主函数为: int main() { int x=7; MyClass *myObj=&MakeObject(x); cout"My object has member"myObj->GetMember()end1; return 0; } 解析:本题考核对象指针的应用。程序中出现了2个出错标识符,说明此程序有2处错误。
    第1处错误:“MyClass*myObj=MakeObject(x);”。myObj是对象指针,而函数 MakeObject( )的返回值是类MyClass的对象,所以应改为:“MyClass *myObj=&MakeObject(x);”。
    第2处错误:“cout"MyObject has member"myObj.GetMember()end1;”。对象指针使用方式有两种:“对象指针名->成员名;”和“(*对象指针名)成员名;”。显然上述语句的对象指针的使用方式是错误的。应改为“cout"My object has member"myObj->GetMember()end1;”,或者“cout"MyObject has member"(*myObj).GetMember()end1;”。

  • 第4题:

    下列给定程序中,函数fun()的功能是:计算整数n的阶乘。

    请改正程序中的错误,使它能得出正确的结果。

    注意:不要改动main函数,不得增行或删行,也不得更改程序的结构。

    试题程序:

    include <stdio.h>

    double fun(int n)

    {

    double result=l.0;

    whil (n>l&&n<170)

    /**************found********************/

    result*=--n;

    /**************found********************/

    return;

    main()

    {int. n;

    clrscr();

    printf("Enter an integer: ");

    scanf("%d",&n);

    printf("\n\n%d!=%lg\n\n ",n, fun(n));

    }


    正确答案:(1)错误:result*=--n; 正确:result*=n--; (2)错误:return; 正确:return result;
    (1)错误:result*=--n; 正确:result*=n--; (2)错误:return; 正确:return result; 解析:该题采用循环语句计算n的阶乘。当n大于1且小于170时,令result与n相乘,同时n自动减1,循环至n=2(n=1时无需相乘):注意:o和1的阶乘都等于1,可用条件语句和循环语句实现上述功能。

    The school trip has become an annual event.

    A:yearly
    B:average
    C:tedious
