fraction.hpp

这些程序是本人学习数据结构时编的

#include<iostream.h>
class Fraction{
public:
   Fraction(int a=0,int b=1);
   Fraction(const Fraction& other);
   Fraction mins1();     //用辗转相除法化简
   Fraction mins2();     //用分解因式化简
   Fraction operator +(const Fraction& other);
   Fraction operator -(const Fraction& other);
   Fraction operator *(const Fraction& other);
   Fraction operator /(const Fraction& other);
   Fraction operator =(const Fraction& other);
   int operator <(const Fraction& other);
   int operator >(const Fraction& other);
   int operator ==(Fraction& other);
   void change(double c);
   Fraction redu(const Fraction& other);
   friend ostream& operator <<(ostream& stream,Fraction& obj); //重载输出符<<
   friend istream& operator >>(istream& stream,Fraction& obj);//重载输入符>>
protected:
   int deno,nume;
};
