下面是小弟的代码，实在找不出问题，请高手们帮忙
求长方住的体积
//volume.h
#include<iostream>
using namespace std;
class volume
{
public:
void set_value();
void multi_value();
void show_value();
private:
int length;
int width;
int height;
int result;
};
//volume.cpp
#include<iostream>
#include"volume.h"
void volume::set_value()
{ int i=0;
for(;i<3;i++)
{
cin>>length;
cin>>width;
cin>>height;
};
}
void volume::multi_value()
{
result=length*width*height;
}
void volume::show_value()
{
cout<<result<<endl;
}
int main()
{ volume v[3];
int j=0;
for(;j<3;j++) v[j].set_value();
for(j=0;j<3;j++) v[j].multi_value();
cout<<v[0].result<<" "<<v[1].result<<" "<<v[2].result<<endl;
return 0;
}

[解决办法]
v[0].result。。。。result是私有成员。。外部不能对其进行直接操作。。你要写一个函数。。用于输出result
