    You \b\b\b your friend should visit and type rand into the search box.

    1) Get the random number in the proper range

    2) Use the >> operator in a while loop conditional to read in words from the file, e.g.:
    3) Keep looping until a loop counter reaches the random number, then break out of the loop, and 'word' will contain the word you want.

    rand() and srand() are in <cstdlib>.
