Repeating words in string class - c++

Question

So I have to write a string class, and I need help with reading from a file into a vector of string classes I've created. It somewhat works, as it reads from the file but it repeats the the word read in a few times depending on which word it's on.
// .h
/*Class description:
A string class. Various functions for the class.
String is passed into objects of the class. Reads
and writes to files.*/

And here is main

}
word.resize(wordCount);
fin.close();endl;
return 0;
}
It doesn't print out to the console any of the words. Nothing is printed. Why doesn't it print?
