1. HANGMAN Created By: Will Matthau & Christian Stumpf

2. Overall Design Introduce the game menu Prompts user for a difficulty level from 1 – 5 User selects difficulty level Difficulty level triggers a random number to pick from 10 words and stores it in that word in the secret_word string –(5 Difficulty Levels, 10 words per level, 50 words) display_word character array is created based upon the length of secret_word and is comprised of only blanks Prints out a picture based on how many wrong guesses the user has from the picture function Prompts user for a guess which is stored in letter letter_check checks whether the letter entered is in secret_word and puts it into display_word and updates it Then it loops and lets the user guess again…

3. Functions explained: 1.void introduction() 2.void pick_difficulty() 3.void make_display_word() 4.void picture() 5.void letter_check() 6.void guess_a_letter()

4. void introduction() This function simply does what it looks like it would – it introduces the program and displays the main menu

5. void pick_difficulty() This function also does what it looks like it would – it prompts the user for the difficulty level that the user wants to try and play at –The difficulty directly relates to the size of the word being chosen Level 1 = easy short words ↨ Level 5 = longer harder words –The difficulty chosen will then correlate to the set of the 10 words that a random number will choose inside the function

6. void make_display_word() The for loop allows this function to display underscores with spaces in between them corresponding to the size of the secret_word chosen in pick_difficulty

7. void picture() This function does what it might appear to do – it outputs the correct picture corresponding to the wrong_guess_count the user has at the current time

8. void letter_check() This function is labeled letter_check since the function checks whether or not the letter guess the user chooses is in the secret_word string –If the function figures out that the letter is in fact in the secret_word, then it places it in the character array where it belongs It does this by utilizing flags and changing their values –If not, then the function does nothing with the display_word array and increments the wrong_guess_count integer

9. void guess_a_letter() This function like the rest of the functions in the project does what it looks like it might – it asks the user to choose a letter from the alphabet to see if its in the secret_word

41. Problems Experienced: random_number was not actually random –The number was always 1, or 41 –Therefore, the first case was always chosen rather then randomly choosing a case for each difficulty level We initially didn’t have globals set so certain functions were not given access to the maximum guess count that we initially set as well as the current users wrong guess count
