Hello, everybody, this is my first question, so please notice me if it's something wrong with this.
I want to replace some words without using boost libraries or other .hpp's.
My first attempt was to make a copy of the string, and it was quite inefficient. I'm not very proud of it, so I will post my second attempt where I use addresses.
void ReplaceString(std::string &subject, const std::string &search, const std::string &replace) 
    size_t position = 0;
    while ((position = subject.find(search, position)) != std::string::npos)	//if something f***s up --> failure
         subject.replace(position, search.length(), replace);
         position = position + replace.length();

Because It's not very efficient I want to use another thing, but I got stuck; I want to use a function like
replace_stuff(std::string & a);
with a single parameter using string.replace() and string.find() (parsing it with a for loop or something) and then make use of std::map <std::string,> which is very convenient for me.

Can anyone help me with this, please? I started learning C++ few months ago, and I don't know many tips and tricks. I also have some problems with my coherence, so please excuse my poor English.
Best regards,

P.S. I want to use it for a large number of input words. (let's say replacing bad words with harmless ones)

Solution 1

You might create a class, say Replacer:
class Replacer 
  std::map<std::string,> replacement;
     // init the map here
     replacement.insert ( std::pair<std::string,std::string>("C#","C++") );
  void replace_stuff(std::string & a);

Then the replace_stuff definition would be very similar to your original ReplaceString (it would use map entries instead of the passed parameters).
