Example

 int  main()  {
     vector<string>  v;
     string  s;
     while  (cin  >>  s)  v.push_back(s);
     vector<string>::iterator  i  =  find_if(
             v.begin(),  v.end(),  compose1(
                 bind2nd(greater<size_t>(),  7),
                 mem_fun_ref(&string::length)));
     cout  <<  *i  <<  endl;
