Listing 18-8: Creating misspelled words and asking the player to fix them
The words array contains the words for this game (line 2). The program
randomly picks a word from the words array and saves that word as strIn
(line 5). Note how we used the array’s item count to set the upper limit of
the random number. The program then selects a random letter, randChar,
from the alphabet (line 6). It does that by getting a random number from 1
to 26 and adding 96 to it; this gives you a random number between 97 (the
code point for letter a) and 122 (the code point for letter z). Next, the program
picks a random position, charPos, in strIn (line 7): this is the position
where the random character is inserted. Then the program creates the misspelled
word and stores it in strOut (lines 9–11).
In line 13, the program asks the player to enter the correct spelling. It
reads the user’s answer (line 14) and converts it to lowercase (line 15). It
then compares the answer with the correct word (line 16). If the player’s
answer matches the original word, the game displays Good Job! (line 17).
Otherwise, the game displays an error message and shows the correct spelling
(line 19). In both cases, the program ends by displaying an empty line
(line 21), and the loop repeats to give the user a new misspelled word.
Here’s a sample run of this program:
Enter correct spelling for [mairror]: miror
Incorrect. It is mirror.
Enter correct spelling for [inteorface]: interface
Good Job!
TRY IT OUT 18-8
Update the program in Listing 18-8 so the misspelled word contains two additional
random letters instead of just one random letter. Also, add more words to the list
for more variety.
Unscramble
Now we’ll create a word scramble game. The program starts with an English
word, scrambles the letters, displays the scrambled word to the player, and
asks them to guess the original word.
