Vector modification of strings

[killua]

I am in a beginning c++ course and we never covered vectors, but I am trying to learn to do things with vectors instead of multidimensional arrays.

I get a error no matching function for call 'replace'.

Also how would I improve this method to make sure it only removes the part of the string of the 2nd vector that contains a , within it?

 // delete duplicate names using set_intersection operator after first
    // unique name for the first two white space or until '
    for(int i = 0; i < newModified.music.size();i++)
    {
        for(int j = i+1; j < newModified.music.size(); j++)
        {
            vector<string> similarity;
            vector<string>::iterator pos;
            set_intersection(newModified.music[i].begin(),newModified.music[i].end(),newModified.music[j].begin(),newModified.music[j].end(),similarity);
            //if the similarities contain a ,
            pos = find(similarity.begin(), similarity.end(), ',');
            /*size_t foundit = similarity.find_first_of(","); */
            if (!pos->empty())
            {
                //delete the similarities in the second vector
                replace(newModified.music[j].begin(), newModified.music[j].end(), similarity, "");
            }
            else
            {
                //do nothing
            }
        }
    }
