(Reading Data from a File) Use an istream_iterator, the copy algorithm and a back_inserter to read the contents of a text file that contains int values separated by whitespace. Place the int values into a vector of ints. The first argument to the copy algorithm should be the istream_iterator object that’s associated with the text file’s ifstream object. The second argument should be an istream_iterator object that’s initialized using the class template istream_iterator’s default constructor—the resulting object can be used as an “end” iterator. After reading the file’s contents, display the contents of the resulting vector.
