Connect Four Redux Connect Four is a two-player board game that's fun to play. It's also fun to watch a replay of a game that you just won. Requirements A program is needed to allow two people to play Connect Four on a computer, the same way we did for assignment 4. The difference is that now when the user is prompted to enter 'q' to quit they will also be given the option to enter 'r' for 'replay', or 'rerun' or 'redux'. A replay will show the empty board and then show the moves as they occurred, at a rate that makes it possible to appreciate the win. The user should then be prompted again for a 'q' or an 'r' or anything else. An example run is shown at the end of this document. Design A linked list should be used to record the moves that the players make. A singly linked list can be used and the code should be in a separate file called slist.c and slist.h. A function to insert a new node at the tail will be needed. A function to free the list is also needed. The details of what is stored in each node is up to you. Implementation The program will be written in C. Try to write your program incrementally by first creating the overall structure with empty functions (stubs) and testing often to see that your program is always working as expected. Testing When testing, you are checking to see that the program satisfies the requirements. Remember that when moving through the stages of requirements, design, implementation and testing, it is often necessary to go back to a previous stage and revisit decisions and make changes. It is always better to make design changes early in a project rather than later.
