Description

In this homework, you will write a 2-player chess game using your hw#05. You will submit your homework via KADI.

 

#function prototypes

 

You will change the signature of isPieceMovable function, and implement some other functions, as well. You are expected to implement functions given below.

 

Signature

 

int isPieceMovable(char *board, char sc, int sr, char tc, int tr); int isInCheck(char* board);

 

int makeMove(char *board, char sc, int sr, char tc, int tr);

 

Parameters

 

char* board : Board array (as defined in hw#05)

 

char sc: The column of the piece at source

 

int sr: The row of the piece at source

 

char tc: The column of the piece at target

 

int tr: The row of the piece at target

 

Return values and function definitions

 

isPieceMovable

 

Defined in hw#05.

 

isInCheck:

 

Checks whether a king is in check or not.

 

If white king is in check, returns 1

 

If black king is in check, returns 2

 

If there is no check, returns 0

 

makeMove:

If move is valid and opponent player’s king is in check, returns 3

 

#notes

 

  • You are free to write any additional functions.

 

  • You will use your own HW#05, using someone else’s homework will be regarded as cheating.

 

  • Sample main function and output of a sample run are given; you should not modify the given main function.

 

  • There are some limitations and modifications from classical chess game to make your homework much easier. You can see the some of them in sample run file.

 

  • The assignment must be your original work. Duplicate or very similar assignments are both going to be considered as cheating.

 

  • Ask your questions via moodle.
