Hi, guys.... trying to write a function that checks to see if a number already exists in a vector... anyway, the function returns true if the number does not exist and false it it does not. the parameter const string& word is the key to the map my problem is that the program crashes. if i take out this function, then it works fine, as long as i dont use it in the main program. i think the problem is in the for loop, because the program again works fine if i comment out the for loop. thanks in advance for any help.. hope i described the prob ok HTML: bool is_not_present( const map<string, vector<int> >& r, const int& line, const string& word) { map<string, vector<int> >::const_iterator i = r.find(word); bool flag = true; for( vector<int>::const_iterator it = i->second.begin(); it != i->second.end(); ++it ){ if( *it == line) flag = false; } return flag; }
