判断两台设备是否属于同一子网的简易程序(C++实现)
作者:互联网
给定ip地址与子网掩码,通过与运算判断是否属于同一子网:
#include<iostream>
#include<string>
#include<vector>
namespace Address{
class Ip_Mask_Address
{
public:
explicit Ip_Mask_Address(const std::string& ipaddress
,const std::string& ipmask)
:ip_adress(ipaddress),ip_mask(ipmask)
{}
private:
void GetBinaryAdress(std::vector<int>& vec,const std::string& adress);
public:
const std::string GetNetAddress();
const std::string GetIpAddress() const{return ip_adress;}
const std::string GetIpMask() const{return ip_mask;}
private:
std::string ip_adress;
std::string ip_mask;
};
void Ip_Mask_Address::GetBinaryAdress(std::vector<int>& vec,const std::string& adress){
std::string temp = "";
for(auto& str:adress){
if(str != '.'){
temp += str;
}else{
vec.push_back(std::stoi(temp));
temp = "";
}
}
vec.push_back(std::stoi(temp));
}
const std::string Ip_Mask_Address::GetNetAddress(){
std::vector<int>vec_ip,vec_mask;
GetBinaryAdress(vec_ip,ip_adress),GetBinaryAdress(vec_mask,ip_mask);
std::string net_address = "";
for(unsigned int i = 0;i < 4;++i){
net_address += (std::to_string(vec_ip.at(i) & vec_mask.at(i)));
if(i != 3) net_address += '.';
}
return net_address;
}
bool IfBelongSameNetWork(Ip_Mask_Address& lhs,Ip_Mask_Address& rhs) {
if(lhs.GetNetAddress() == rhs.GetNetAddress() && lhs.GetIpAddress() != rhs.GetIpAddress()){
return true;
}else return false;
}
}
void test(){
using namespace Address;
Ip_Mask_Address address_1("192.168.182.131","255.255.255.0");
Ip_Mask_Address address_2("192.168.26.131","255.255.255.0");
if(IfBelongSameNetWork(address_1,address_2)) std::cout<<"They are in the same network\n";
else std::cout<<"Not in the same network\n";
}
int main(){
test();
return 0;
}
