使用VC6打开考生文件夹下的工程test19_1,此工程包含一个源程序文件test19_1.cpp,但该程序运行有
1:
weight:5
age:0
2:
weight:7
age:9
源程序文件test19_1.cpp 清单如下:
include <iostream.h>
class animal
{
public:
/**************** found *******************/
friend void setvalue(animal&,int);
/**************** found *******************/
void print()
protected:
int itsweight;
int itsage;
};
void animal::print()
{
cout<<"weight:"<<itsweight<<end1;
cout<<"age:"<<itsage<<end1;
}
void setvalue(animal &ta,int tw)
{
ta.itsweight=tw;
ta.ihsage=0;
}
void setvalue(animal &ta,int tw, int tn)
{
ta.itsweight=tw;
ta.itsage=tn;
}
void main()
{
/**************** found *******************/
animal peppy
setvalue(peppy,5);
cout<<"1:"<<end1;
peppy.print();
setvalue(peppy,7,9);
cout<<"2:"<<end1;
peppy.print();
}
