Answer:

#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.
