问题描述：设计一个IP地址类，用于保存IP地址，并实施在IP地址上一些操作。
程序输入：

#include <iostream>using namespace std;class IP{private:    union    {        struct        {            unsigned char seg0;            unsigned char seg1;            unsigned char seg2;            unsigned char seg3;        };        unsigned int address;    };public:    IP(int=0,int=0,int=0,int=0);    void showIP();    bool sameSubnet(const IP &ip, const IP &mark);    char whatKind();};IP::IP(int seg00,int seg01,int seg02,int seg03){    seg3=seg00;    seg2=seg01;    seg1=seg02;    seg0=seg03;}void IP::showIP(){    cout<<int(seg3)<<"."<<int(seg2)<<"."<<int(seg1)<<"."<<int(seg0)<<endl;    return;}bool IP::sameSubnet(const IP &ip, const IP &mark){    unsigned int a, b;    a=address&mark.address;    b=ip.address&mark.address;    return (a==b);}char IP::whatKind(){    if(seg3<128)        return 'A';    else if(seg3<192)        return 'B';    else if(seg3<224)        return 'C';    else if(seg3<240)        return 'D';    else        return 'E';}int main(){    IP ip1(202,194,116,97), ip2(202,194,119,102), mark(255,255,248,0);    cout<<"ip1: ";    ip1.showIP();    cout<<"ip2: ";    ip2.showIP();    if(ip1.sameSubnet(ip2,mark))        cout<<"两个IP在同一子网"<<endl;    else        cout<<"两个IP不在同一子网"<<endl;    cout<<"ip1属于"<<ip1.whatKind()<<"类网络"<<endl;    return 0;}

运行结果：
