第2题：

使用VC6打开考生文件夹下的工程test17_1，此工程包含一个源程序文件test17_1．唧，但该程序运行有问题，请改正程序中的错误，使程序的输出结果如下：

Vehicle message

Car message

Vehicle message

源程序文件test17_1.cpp 清单如下:

include ＜iostream.h＞

class vehicle

{

int wheels;

float weight;

public:

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

void message(void){ cout＜＜"Vehicle message\n";}

};

class car:public vehicle

{

int passenger_load;

public:

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

void message (void){cout＞＞"Car message\n";}

};

class truck:public vehicle

{

int passenger_load;

float payload;

public:

int passengers(void){return passenger_load;}

};

void main()

{

vehicle * unicycle;

unicycle=new vehicle;

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

unicycle.message()

delete unicycle;

unicycle=new car;

unicycle-＞message();

delete unicycle;

unicycle=new truck;

unicycle-＞message();

delete unicycle;

}


正确答案：(1)错误：void message(void){cout"Vehicle message\n"；} 正确：virtual void message(void){cout"Vehicle message\n"；} (2)错误：void message(void){cout＞＞"Carmessage\n”；} 正确：void message(void){eout"Carmessage\n"；} (3)错误：unicycle．message()； 正确：unicycle-＞message()；
(1)错误：void message(void){cout"Vehicle message\n"；} 正确：virtual void message(void){cout"Vehicle message\n"；} (2)错误：void message(void){cout＞＞"Carmessage\n”；} 正确：void message(void){eout"Carmessage\n"；} (3)错误：unicycle．message()； 正确：unicycle-＞message()； 解析：(1)主要考查考生对于虚函数使用规则的掌握，要实现对函数message的动态联编应该使用虚函数，否则产生的是静态联编，调用的函数输出结果就与要求不符；
(2)主要考查考生对于流输出操作的掌握，该处错误的使用了流输入操作；
(3)主要考查考生是否能分清对象和对象指针，对象指针使用“-＞”调用成员函数，而对象使用“．”调用成员函数。
