could something like this work? I've looked at guides and they don't seem to work for replacing a single char with two or more chars.

 for (int i = 0; i < s.length(); i++){ if(s[i] == '\"') s[i] = '\"\"'; } cout << s;

    Reminder: use '' for single characters. Use "" for multiple characters. Also, you can't assign multiple characters to a single character slot. Commented Aug 22, 2017 at 20:29
  • You could search the std::string section of your favorite references to see if there are any methods to help you insert characters into a string. Commented Aug 22, 2017 at 20:31
  • try to write the result into a new string; probably easier. Commented Aug 22, 2017 at 20:32

Your code will not perform as you expect.

You are telling std::string to assign a 2 character constant, '\"\"', into a slot that holds a single character.

Search the basic_string section of your favorite C++ reference to find a method to insert a string or multiple characters into a string.

Edit 1 - Example 

std::string::size_type position = 0; position = s.find('"'); while (position != std::string::npos) { s.insert(position, "\""); position += 2; position = s.find('"'); }
