  • row: holds the row vector
  • col: holds the column vector.
  • board: The board(matrix) is created using this variable.
  • result: It is used to create a condition (result==true) for while loop. The loop works until the given condition is true.
  • column: Holds the number of column, player 1 wants to drop the red piece on.
  • column2: Holds the number of column, player 2 wants to drop the black piece on.
  • test: Holds the number ‘2’ assigned to red piece.
  • test2: holds the number ‘3’ assigned to black piece.
  • c: Holds the range of column for which ‘for loop‘ will run.
  • r: Holds the range of row for which for loop will run.
  • gameover: Holds the object ‘gameover.jpg’ which will be displayed once either of the players win.

Description: 

  1. Connect Four begins by asking the players to enter the column number where they want to drop their piece in 6 x 7 board. The players drop the piece alternatively.
  2. If the players enter any other number which is not in the 1 to 7 range , the program will keep asking for another input until the players enter the number between 1 to 7.
  3. Once the player drops the piece, the program will check if their is any winning condition (horizontal, vertical or diagonals).
  4. If any of these condition is present, the program will display who the winner is and if not, the program will ask for another player input and repeat the step 2 and 3.
  5. It will repeat the step 1 to 4 until the board is full. If nobody wins and board is full, the program will displays error.
  6. In order to play the game again, the player will need to hit run.

 

Over Under

Over Under program is created using and input function, rand operator, and an if-elseif-else statement.

1. The input function asks the player to pick Over 5, Under 5, or Equal to 5.

2. The rand operator generates a random number one through ten.

3. The if-elseif -else statement issues and fprintf statement which lets the player know if they were correct or incorrect.
