题目：

根据给定头文件写cpp文件

/********** BEGIN **********/
#include"Int.h"

int Int::getValue()const{return value;}
void Int::setValue(int v){value=v;}
Int::Int(){value=0;}
Int::Int(int v){value=v;}
Int::Int(const Int&rhs){this->value=rhs.getValue();}
Int::~Int(){ }

Int& Int::operator=(const Int&rhs){this->value=rhs.getValue();return *this;}
Int& Int::operator+=(const Int&rhs){this->value+=rhs.getValue();return *this;}
Int& Int::operator-=(const Int&rhs){this->value-=rhs.getValue();return *this;}
Int& Int::operator*=(const Int&rhs){this->value*=rhs.getValue();return *this;}
Int& Int::operator/=(const Int&rhs){this->value/=rhs.getValue();return *this;}
Int& Int::operator%=(const Int&rhs){this->value%=rhs.getValue();return *this;}

Int& Int::operator++(){this->value+=1;return *this;}
Int& Int::operator--(){this->value-=1;return *this;}

Int Int::operator++(int tmp){Int temp=*this;this->value+=1;return temp;}
Int Int::operator--(int tmp){Int temp=*this;this->value-=1;return temp;}
