Removing Characters from a String

found an interesting learning resource http://www.bogotobogo.com/it also has a section on programming questions, not so extensive as the awesome http://geeksforgeeks.org/, but has some good problems to solve, with solutions. here is my solution to the "Removing Characters from a String" problem (http://www.bogotobogo.com/cplusplus/quiz_strings_arrays.php). it is not better, just a different approach

#include 
#include 

int main()
{
  std::string name("Ludwig Van Beethoven");
  std::string remove("aeiouAEIOU");
  int walk = 0;
  int last = 1;
  while (last < name.length() && walk < name.length()) {
      auto found = remove.find(name[walk], 0);
      if (found != std::string::npos) {
          char ch = name[walk];
          name[walk] = name[last];
          name[last] = ch;
          ++last;
      } else {
          ++walk;
      }
  }
  std::cout <<"Hello, "<< name.substr(0, walk+1) <<"!\n";
}
