定义一个分数类rational，其中有两个私有的整型成员变量，分子numerator和分母denominator，分母不为0。重载运算符+和+=实现分数加法运算，要求运算结果为最简分数。（class rational

private:
int numerator; //分子
int denominator; //分母
public：
rational(int a=0,int b=1);
void optimization();//实现分数的有理化，即分子分母的最简化
void print(); //分数的输出
rational & operator+=( const rational & num);//成员函数重载运算符+=
friend rational operator+(const rational & num1,const rational & num2);
//友元函数重载运算符+
;

#include<iostream>
#include<cmath>
using namespace std;
class point

friend istream&operator>>(istream&is,point&p);
friend ostream&operator<<(ostream&os,point&p);
public:
point(double x0=0,double y0=0)x=x0;y=y0;
point(point &);
point operator+(const point & pt);
double operator^(const point & pt);

private:
double x,y;

;
point::point(point &p)

x=p.x;
y=p.y;
;
istream&operator>>(istream&is,point&p)

return is>>p.x>>p.y;

;
ostream&operator<<(ostream&os,point&p)

return os<<"("<<p.x<<","<<p.y<<")";

;
point point::operator +(const point &pt)

return point(x+pt.x,y+pt.y);

;
double point::operator ^(const point &pt)

return sqrt((x-pt.x)*(x-pt.x)+(y-pt.y)*(y-pt.y));



int main()

point p1,p2,p3;
double c;
cin>>p1;
cin>>p2;
p3=p1+p2;
c=p1^p2;
cout<<p3<<endl;
cout<<c;
return 0;

我百度里面搜来的。。我的空间就是这首歌，应该还能用的。

各路大神帮帮忙 谁有Arcgis Server 10.2.2许可文件，在线等~~拜托了各位

将下面代码放入txt,然后修改后缀名为ecp，那个文件就是你要的许可文件。
