The number of words this problem feel with C write very troublesome, write in C + + is relatively simple. Not much to say, direct sticker code.

#include <iostream>#include<string>#include<vector>#include<sstream>using namespacestd;intmain () {vector<string>s; strings0,s1; intFlag;  while(Getline (CIN,S0)) {if(s0=="#")             Break; Else{s.clear ();            Istringstream sin (s0);  while(sin>>S1) {Flag=0;  for(intI=0; I<s.size (); i++)                {                    if(s[i]==S1) {Flag=1;  Break; }                }                if(flag==0) S.push_back (S1); } cout<<s.size () <<Endl; }    }    return 0;}

Feel the use of set is simpler, this is the online code:

#include <iostream>#include<Set>#include<string>#include<sstream>//don't forget it. using namespacestd; intMain () {stringArt;  while(Getline (cin,art) && Art! ="#") {Istringstream stream (art); stringWord; Set<string>map;  while(Stream >>word)            {Map.insert (word); } cout<<map.size () <<Endl; }        return 0; }
