Question

Write a MATLAB code for the hangman game below you might break the problem down into:

• Selecting a word from a dictionary. ‘aardvark’
• Reading a single letter from the user like ‘a’
• Building a character array showing the letters matched so far like ‘aa---a--’
• Keeping count of the number of guessed letters so far.
• Keeping count of the number of guesses so far.
• Writing conditional logic to see whether the game is finished or not.

Answer 1

Code

words = {'apple','football','banana','grapes','criciketer','offside','watermelon','pineapple','avacado'}; % list of words
random_index = ceil(length(words)*rand()); % select random index
random_word = words{random_index}; % selct random word
guessed_chars = {};
number_guesses = 0;
next_iteration = true;
while next_iteration % run until broken
next_iteration = false;
for i=1:length(random_word) % for each alphabet
guessed = false; % was this in guessed alphabet
for j=1:length(guessed_chars)
if random_word(i) == guessed_chars{j} % check if this psecific charactr was guessed
fprintf(random_word(i)) % show it
guessed = true;
break
end
end
if(~guessed)
fprintf('-') % put a dash if character has not been guessed yet
next_iteration = true;
end
end
if(~next_iteration)
break
end
input_char = input('\nEnter char : ','s'); % input char
guessed_chars = [guessed_chars input_char]; % add to guessed chars

number_guesses = number_guesses + 1; % count number of guesses
end
fprintf('\n Number of guesses : ')
disp(number_guesses)

Output Run
