回答1:

第一题改写程序:
#include
using namespace std;
class Time //定义Time类
{public:
void input()
{
cin >> hour >> minute >> sec;
}
void display()

{
cout << hour << minute << sec;

}

private:
int hour;
int minute;
int sec;
};
int main( )
{ Time t1;
t1.input();
t1.display();
system("pause");
return 0;
}
第二题:成员函数set_value如下:

void student::set_value(int _num,char *_name,char _sex)

{
num = _num;

strcpy(name,_name);
sex = _sex;

}
第三题:
class Column
{
Colume(){}

Colume(float _length,float _width,float _height)

{
length =_length;

width = _width;

height = _height;

}

public:

float cal_volume()
{
return length*width*height;
}
void display()

{

cout << cal_volume() << endl;

}
private:

float length;
float width;

float height;

};
主函数你自己写吧
