Ti si ovo prijatelju pogrešno prekucao. Pazi ovo:

void initialize_exclusion_set(set<string> &exs) {
static string _excluded_words[25]={
"the", "and", "but", "that", "then", "are", "been",
"can", "a", "could", "did", "for", "of",
"had", "have", "him", "his", "her", "its", "is",
"were", "which", "when", "with", "would"
};

exs.insert(_excluded_words, _excluded_words+25);

Šta ex.insert radi tu, van svih funkcija?

A pazi tek ovaj biser:

set<string> exclude_set;
initialize_exclusion_set(exclude_set);
map<string,int> word_count;
process_file(word_count, exclude_set,ifile),
user_query(word_count);
display_word_count(word_count, ofile);
getchar();
}

Pogledaj to malo bolje, pa se onda javi. To što si poslao SIGURNO ne piše u knjizi. Ako stvarno piše, bolje je baci.
