c++ - Creating a highscore system using Vectors -

im learning c++ , directx 9. creating small game want have high score system, have reading , writing of files done, stuck on how sort , insert new value score vector.

my method reading files vector below:

     vector<int> highscore::readfile()      {       int score;        highscorein.open ("highscore.txt", ios::out | ios::binary);        if (highscorein.is_open())        {         while(highscorein>>score)          {            scores.push_back(score);          }          highscorein.close();     return(scores);        }        else cout << "unable open file";       } 

i want function check integer passed function against 5 values storing in vector scores, insert right place in vector. on appreciated:)

assuming vector sorted largest smallest

bool insert( vector<int> &v, int n ) {     ( auto = v.begin(); != v.end(), ++it ) {         if ( *it < n ) {             v.insert( it, n );             v.pop_back()             return true;         }      }      return false; }
