Connect Four is a game that alternates player 1 and player 2. You should keep track of whose turn it is next. For this program we will just be building the structure not the full program.

Your assignment: Create a two player Connect Four C language program that follows the requirements below.

Create functions:

  • Initialization – print “Setting up the game”. Ask each player their name.
  • Teardown – print “Destroying the game”
  • Accept Input – accept a letter for which column of the game we are going to drop a disc into. Valid letters are A-G (7 columns). You should designate a letter for “Quit the game”. Input must be returned from this function.
  • Update the state of the world – pass the input data to this function. Since we do not have a “world” right now, choosing “A” is the “winning move”, all other letters make the game continue. This method must not print anything. It only does calculations. Results from here update the “global state.”
  • Display the state of the world – Print the result calculated in the state of the world. Later, this should print the board.
  • Main – call initialization, then loop until a flag is set (game over or a player quit), calling accept input, update and display. Outside of the loop, call teardown.

Make variables to define the size of the board (width and height). These can be global variables. Other global variables might include player names, which player should play next and “did anyone quit yet?” If you consider the game board in Connect Four carefully, you can see that it is a two-dimensional grid of squares. When a player deposits a disc in a column, the disc must “fall” until it is either just above the bottom (i.e. in the last row) or it is sitting upon another disc. There are many models that we could use for this, but for this assignment, we will use a simple two-dimensional array.

There are a number of additional requirements for the Connect Four program that we need to do in order to complete our game, make sure your program includes the following:

  1. We need to allocate the space for the game board. While this is a fixed size board, we will still dynamically allocate the space for the board in the initialization function.
  2. Whenever we allocate memory, we need to make sure that we free it as well. Free the memory in the teardown function.
  3. Print the game board in the display the world function. Use one character for an empty spot, one character for the discs for player one and another character for the discs for player two. You may use whatever characters you prefer. You may make the display as complex as you wish so long as we can clearly see what moves are available.
  4. The remainder of the work to be done goes into “update the state of the world.”
    1. We must look through the column of the array and add the new disc into the array in the appropriate location based on the column that the player chose.
    2. We must signal to end the game if the column that the player chose is full.
    3. We must look for 4 discs belonging to one player in a straight line. The line can be horizontal, vertical, or diagonal. When we find this, we must signal end of the game.

With these changes, we can now play the game with players taking turns at the keyboard.

Coin taking game This game is played between 2 players, player 1 and player 2. There are two piles of coins. The values of a coin can be any integer. Both players know the values of all coins in both piles. Player 1 makes the first move, and play alternates between the players. A move consists of taking a coin from the top of either of the piles (either player can take from either pile). The game ends when both...

Using c++ Design a system to keep track of employee data. The system should keep track of an employee’s name, ID number and hourly pay rate in a class called Employee. You may also store any additional data you may need, (hint: you need something extra). This data is stored in a file (user selectable) with the id number, hourly pay rate, and the employee’s full name (example): 17 5.25 Daniel Katz 18 6.75 John F. Jones Start your main...

In a lottery game a player chooses four digits (digits can repeat, for instance 0, 2, 0, 2 is a valid choice) and bet $1 that all four of them will arise in the four digit number drawn from the lottery. It isn’t necessary that the order will be the same: if a player selects 2, 6, 7, 8 the selection of 8, 2, 7, 6 means he won. Player gets $200 if he wins. 1. What is the probability...

Consider a game in which, simultaneously, player 1 selects any real number x and player 2 selects any real number y. The payoffs are given by: u1 (x, y) = 2x − x2 + 2xy u2 (x, y) = 10y − 2xy − y2. (a) Calculate and graph each player’s best-response function as a function of the opposing player’s pure strategy. (b) Find and report the Nash equilibria of the game. (c) Determine the rationalizable strategy profiles for this game.
