Activity 2: Play the "horse" Game Using Functions Defined in Activity 1 Unzip the Activity2.zip file. Under the lab directory, there should be two directories, a makefile, and file called 'dictionary.txt'. Navigate to the 'src' directory and open gameFunctions.c in the editor of your choice. There are several functions already fully implemented in this file. You should copy all the functions you implemented in Activity 1 and paste them in this file 1. 2. 3. Navigate to the 'include' directory and open gameFunctions.h in the editor of your choice. 4 Complete the function prototypes that you implemented in gameFunctions.c here. 5. Complie the program using the make command and complete the worksheet.

Explanation / Answer

Below are the modified files according to the question. Used the functions from your Activity, some functions had a different order of parameters, just rearranged the parameters order in the signature and retained the function body as it is. Added a function checkGuess() to work using the checkLetter() which was already implemented.

Please post a comment if you have any doubts/issues, I shall respond. Please rate the answer if it helped. Thank you very much.
