Project Details:
Your program should read in a random word from a file called words.txt (note the lack of
capitalization) that you provide. The file should contain one word per line. To read a random
word you can generate a random number between 1 and the number of lines, and skip n-1 lines
before reading the word. Scramble the word by swapping random pairs of letters a random
number of times. Display the scrambled word with character indexes on top. Offer the user a
menu with the following choices:
• Enter 1 to swap a pair of letters
If this option is selected prompt the user to enter two indexes and swap the letters. Print an error
message if the indexes are invalid. If the word is unscrambled successfully print a congratulatory
message containing the word and the number of steps it took to unscramble. Otherwise display
the new word, and offer the menu again.
• Enter 2 to solve
If this option is selected print the unscrambled word and quit.
• Enter 3 to quit
If this option is selected quit.
