一：

#include<iostream>
using namespace std;
class basic
{
	public:
		basic(int a,int b):m(a),n(b){}
		~basic(){}
		void jia()
		{
			cout<<m+n<<endl;
		}
	private:
		int m,n;
};
class A:public basic
{
	public:
		A(int a,int b):basic(a,b),m(a),n(b){}
		~A(){}
		void jian()
		{
			cout<<m-n<<endl;
		}
	private:
		int m,n;
}; 
class B:public basic
{
	public:
		B(int a,int b):basic(a,b),m(a),n(b){}
		~B(){}
		void cheng()
		{
			cout<<m*n<<endl;
		}
	private:
		int m,n;
};
class C:public basic
{
	public:
		C(int a,int b):basic(a,b),m(a),n(b){}
		~C(){}
		void chu()
		{
			cout<<m/n<<endl;
		}
	private:
		int m,n;
};
int main()
{
	int i,j;
	cin>>i>>j;
	A a(i,j);
	B b(i,j);
	C c(i,j);
	a.jian();
	b.cheng();
	c.chu();
	return 0;
}

二：

#include <iostream>
using namespace std;
class vehicle
{
public:
    vehicle(int ,int );
    ~vehicle();
    void run();
    void stop();
private:
    int maxspeed;
    int weight;
};
vehicle::vehicle(int a,int b):maxspeed(a),weight(b)
{
    cout<<"constructing vehicle"<<endl;
    cout<<"maxspeed:"<<maxspeed<<endl;
    cout<<"weight:"<<weight<<endl;
}
vehicle::~vehicle(){}
void vehicle::run()
{cout<<"run"<<endl;}
void vehicle::stop()
{cout<<"stop"<<endl;}


class bicycle:virtual public vehicle
{
public:
    bicycle(int ,int ,int );
    ~bicycle();
private:
    int height;
};
bicycle::bicycle(int a,int b,int c):vehicle(a,b),height(c)
{
    cout<<"constructing bicycle"<<endl;
    cout<<"height:"<<height<<endl;
}
bicycle::~bicycle(){}

class motorcar:virtual public vehicle
{
public:
    motorcar(int ,int ,int );
    ~motorcar();
private:
    int seatnum;
};
motorcar::motorcar(int a,int b,int c):vehicle(a,b),seatnum(c)
{
    cout<<"constructing motorcar"<<endl;
    cout<<"seat:"<<seatnum<<endl;
}
motorcar::~motorcar(){}

class motorcycle:public bicycle,public motorcar
{
public:
    motorcycle(int ,int ,int ,int );
    motorcycle();
    ~motorcycle();
};
motorcycle::motorcycle(int a,int b,int c,int d):vehicle(a,b),bicycle(a,b,c),motorcar(a,b,d){}
motorcycle::~motorcycle(){}

int main()
{
    motorcycle car(100,100,2,4);
    car.run();
    car.stop();
    return 0;
}

三：

#include "Fraction.h"
#include <iostream>
using namespace std;
Fraction::Fraction(int i,int j):top(i),bottom(j){}
Fraction::Fraction(int i):top(i)
{
    bottom=1;
}
Fraction::Fraction()
{
    top=0;
    bottom=1;
}
Fraction::~Fraction(){}
Fraction Fraction::operator+(Fraction &b)
{
    Fraction temp;
    temp.top=top*b.bottom+b.top*bottom;
    temp.bottom=bottom*b.bottom;
    return temp;
}
Fraction Fraction::operator-(Fraction &b)
{
    Fraction temp;
    temp.top=top*b.bottom-b.top*bottom;
    temp.bottom=bottom*b.bottom;
    return temp;
}
Fraction Fraction::operator*(Fraction &b)
{
    Fraction temp;
    temp.top=top*b.top;
    temp.bottom=bottom*b.bottom;
    return temp;
}
Fraction Fraction::operator/(Fraction &b)
{
    Fraction temp;
    temp.top=top*b.bottom;
    temp.bottom=bottom*b.top;
    return temp;
}
void Fraction::divide(Fraction &a)
{
    cout<<top*a.bottom<<"/"<< bottom * a.top << endl;
}
void Fraction::compare(Fraction &a)
{
    if(top*a.bottom>bottom*a.top)
        cout<<top<<"/"<<bottom<<endl;
    else if(top*a.bottom<bottom*a.top)
        cout<<a.top<<"/"<<a.bottom<<endl;
    else if(top*a.bottom==bottom*a.top)
        cout<<"一样大"<<endl;
}
void Fraction::input()
{
    cin>>top>>bottom;
}
void Fraction::output()
{
    cout<<top<<"/"<<bottom<<endl;
}

#ifndef Fraction_h 
#define Fraction_h
class Fraction
{
public:
    Fraction(int i,int j);
    Fraction(int i);
    Fraction();
    ~Fraction();
    Fraction operator+(Fraction &b);
    Fraction operator-(Fraction &b);
    Fraction operator*(Fraction &b);
    Fraction operator/(Fraction &b);
    void divide(Fraction &a);
    void compare(Fraction &a);
    void input();
    void output();
private:
    int top;
    int bottom;
};
#endif

#include"Fraction1.h"
class iFraction:public Fraction
{
    public:
        iFraction(int x=0,int y=1,int z=0):Fraction(x,y),zheng(z){}
        void print();
        friend iFraction convertF(iFraction &d); 
    private:
        int zheng;
};

#include"iFraction.h"
#include<iostream>
#include<iomanip>
using namespace std;
void iFraction::print()
{
    if(top==0)
        cout<<setw(4)<<zheng<<endl;
    else if(zheng==0)
    {
        cout<<setw(4)<<top<<endl;
        cout<<setw(4)<<‘-‘<<endl;
        cout<<setw(4)<<bottom<<endl;
    }
    else
    {
        cout<<setw(4)<<top<<endl;
        cout<<setw(3)<<zheng<<‘-‘<<endl;
        cout<<setw(4)<<bottom<<endl;
    }
}
iFraction convertF(iFraction &d)
{
    d.simplify(); 
    d.zheng+=d.top/d.bottom;
    d.top%=d.bottom;
    return d;
}

#include <iostream>
#include "iFraction.h"
using namespace std;
int main()
{
    Fraction a(-6,8);
    Fraction b(5);
    Fraction c;
    cout<<"a=";
    a.show();
    cout<<"b=";
    b.show();
    cout<<"c=";
    c.show();
    c=a+b;
    cout<<"c=a+b=";
	c.show();
    c=a-b;
    cout<<"c=a-b=";
	c.show();
    c=a*b;
    cout<<"c=a*b=";
	c.show();
    c=a/b;
    cout<<"c=a/b=";
	c.show();
    iFraction d(9,6,5);
    cout<<"d="<<endl;
    d.print();
    d=convertF(d);
    cout<<"规范化处理"<<endl;
    d.print(); 
    return 0;
}

 

这是我操作时出现的问题，我也不知到这么解决，我点一下main就会自动新建一个main，然后我写了数据的那个删都删不掉。

五：

这次的实验还是比较简单比较少的（附加是什么？）
