Thread: Sudoku problem!!

Hello Again.

I want to make Sudoku Game In C.

But I have problem for solution. Please help me.

Code:

  #include <stdio.h>#include <stdlib.h>

 

enum {BORDER,EMPTY};

const int ConvertTo25[25]= {

	8,9,10,11,12,

	15,16,17,18,19,

	22,23,24,25,26,

	29,30,31,32,33

};

 

void GetDifferentRandomNumber(int *board)

{

	int index = 0;

	int loopIndex;

	int moveOk = 0;

	int randomNumber[5];

	int newNumber;

	while(moveOk!=5)

	{

		for(index = 0;index < 5;)

		{

				newNumber = (1+rand()%5);

				if(ControlDifferentNumber(&randomNumber,newNumber)==1)

				{

					randomNumber[index]	= newNumber;

					board[ConvertTo25[index]] = randomNumber[index];

					index++;

				}

		}

	moveOk=5;

	}

}

int ControlDifferentNumber(int *randomNumber, int newNumber)

{

	int index = 0;

	for(index = 0; index<5 ; index++)

	{

		if(randomNumber[index]==newNumber)

		return 0;

	}

	return 1;

}

 

void PrintBoard(const int *board)

{

	int index = 0;

	char pChar[2]="|-";

	printf("\n");

	for(index = 0; index<25; ++index)

	{

		if(index!=0 && index%5==0)

		{

			printf("\n\n");

		}

		printf("%5d",board[ConvertTo25[index]]);

	}

		printf("\n");

}

 

void InitiazeBoard(int *board)

{

	int index;

	for(index = 0; index<49; ++index)

	{

		board[index] = BORDER;

	}

	

	for(index = 0; index<25; ++index)

	{

		board[ConvertTo25[index]] = EMPTY;

	}

}

void RunGame()

{

	int board[49];

	InitiazeBoard(&board[0]);

	GetDifferentRandomNumber(&board[0]);

	PrintBoard(&board[0]);

}

int main(void) {

	srand(time(NULL));

	RunGame();

	return 0;

}

What are 5, 25 and 49 supposed to be?

Especially since a sudoku board is 9x9.

So start with

Code:

#define SIZE 5

And replace all those magic numbers with SIZE or SIZE*SIZE, or whatever seems appropriate.
It will go a long way to making the code readable.

Also, saying "it doesn't work" without saying what you want to achieve is pretty meaningless as well.
