Remove spaces from std::string in C++

Question

What is the preferred way to remove spaces from a string in C++? I could loop through all the characters and build a new string, but is there a better way?

Answer 1

   #include 
   using namespace std;

   int main() {
       .
       .
       s.erase( remove( s.begin(), s.end(), ' ' ), s.end() );
       .
       .
   }
