Write a code segment that takes an emailaddress stored in the string email and stores theuser name in the string user and the hostaddress in the string host. remember that the user name and host address are separated by thecharacter @.

#include <bits/stdc++.h>

using namespace std;

int main() {

  string email,username,host;//strings to store email,username,hostname..

  cout<<"Enter the email address "<<endl;

  cin>>email;//taking input of email address..

  bool flag=1;

  for(int i=0;i<email.length();i++)//iterating over the string email..

  {

      if(email[i]=='@')//if @ symbol is encountered make flag 0 skip this iteration.

      {

          flag=0;

          continue;

      }

      if(flag==1)//add to username if flag is 1.

      {

          username+=email[i];

      }

      else//add tom host..

      host+=email[i];

  }

  cout<<"The username is "<<username<<endl<<"The host name is "<<host;//printing the username and hostname..

return 0;

}

Explanation:

I have taken  three strings to store the email address entered by user ,username and host to store username and host name respectively.Then I am iterating over the string email if @ is encountered then skip that iteration before that keep adding characters to username string and after that keep adding characters to host.

omg taking this same test i was stuck on the same question i was too lazy to read the book sadly i cant really give you an answer to this question too complex the answer will be in chapter 5 of the cay
