Question

How can I in C++ remove all specified characters from the string?
For example If I have a string " &New &York " and I want to remove the characters from the set {' ','&'} ,the string after removing will look like "NewYork".
I prefer not to write a function which iterates a string and checks for each char in string if it is part of the undesired set.

You can try this:

str.erase(
  std::remove_if(str.begin(), str.end(), [](char chr){ return chr == '&' || chr == ' ';}),
  str.end());
