第8题:

使用VC6打开考生文件夹下的工程test16_1,此工程包含一个源程序文件test16_1.cpp,但该程序运行有问题,请改正程序中的错误,使程序的输出结果为:

Which act(a or b)?b

act1

act2

Bact3

Bact4

Bend

源程序文件test16_1.cpp清单如下:

include<iostream.h>

class A

{

public:

virtual void act1(){cout<<"actl\n";act2();}

void act2(){cout<<"act2\n";act3();}

/**********+****** found *****************/

void act3(){cout<<"Aact3\n";act4();}

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

virtual void act4{cout<<"Aact4\n";act5();}

void act5(){cout<<"Aend\n";}

};

class B:public A

{

void act3(){cout<<"Bact3\n";act4();}

void act4() {cout<<"Bact4\n";act5() ;}

void act5() {cout<<"Bend\n";}

};

void main (void)

{

char c;

A *a;

cout<<"Which act (a or b) ?";

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

cin<<c;

if(c=='a')

a = new A;

else

a = new B;

a->act1 ( );

delete a;

}


正确答案:(1)错误:voidact3(){cout"Aact3\n";act4();} 正确:virtual void act3(){cout"Aact3\n";act4();} (2)错误:virtual void act4{cout"Aact4\n";act5();} 正确:virtual void act4(){cout"Aact4\n";act5();} (3)错误:cinc; 正确:cin>>c;
(1)错误:voidact3(){cout"Aact3\n";act4();} 正确:virtual void act3(){cout"Aact3\n";act4();} (2)错误:virtual void act4{cout"Aact4\n";act5();} 正确:virtual void act4(){cout"Aact4\n";act5();} (3)错误:cinc; 正确:cin>>c; 解析:(1)主要考查考生对于虚函数使用规则的理解,要实现对函数act3的动态联编应该使用虚函数,这样在本题中对于函数的调用才能实现根据不同对象调用不同函数;
(2)主要考查考生对于函数定义的掌握,虽然参数表为空,但括号是不能省略的:
(3)主要考查考生是否会使用流输入操作,本题中使用的是流输出符。
