Возможен ли в С++ ввод символов без пробелов?

#include<iostream>
#include<string>

using namespace std;

using mytype = pair<string, int>;

istream& operator>>(istream& is, mytype& m)
{
  while(isalpha(is.peek()))
  {
    m.first.push_back(is.get());
  }
  is >> m.second;
  return is;
}

ostream& operator<<(ostream& os, const mytype& m)
{
  return os << m.first << m.second;
}


int main()
{
  mytype mt;

  cin >> mt;

  cout << mt << endl;
}
