debug assertion failed!

[ramus313]

this program scans a text file to see if words exist in it. this is not the whole program, so the random characters are not relevant to the program yet, but the program searches a vector containing approximately 38,000 words, and if it is there, then it prints "Correct!". the program works, but at the end it says "debug assertion failed!
Expression: vector subscript out of range"

#include <iostream>
    #include <string>
    #include <vector>

    using namespace std;
	 vector<string> words;

	 string word;
	 char randchars[6];

	 void load_file(){
	 ifstream file;

		file.open("");
		
		file.open ("c:\\TEXT TWIST\\words.txt");

		std::string word;
		if(file.is_open()){

while(file >> word)
{
    words.push_back(word);
	
}


		cout<<"@@@@MAIN@@@@@"<<endl;

In your for loops you make one iteration to much. You should replace <= with < in you loop conditions.

thank you so much!!!
