Thread: Mine sweeper help needed

Hi guys,
I'm in need for some help in my homework assignment. I'm kind of new at C programming.

My problem is that for some reason when I print the board, the i counter jumps to astronomical number.
I placed an *?* on that line. (it's down below)
Oh and a major problem that I thought it was me but the debugger shows the board[][] after calling the mainProgram and transferring the board as board[], meaning it now has only 1 dimension (???).

Thanks for helping !

Code:

#include <stdio.h>
#define N 9
#define A 40

void mainProgram(char board[N][N]);
int input_mines(char board[N][N],int size);
void mainMenu();
int insertMine(char board[N][N],int size, char mines[40]);
void printBoard(char board[N][N],int size);


int main()
{
	char board[N][N]={'0'};
	mainProgram(board);
	printf("Bye, please press enter to exit!\n");
	getchar();
	return 0;
}

void mainProgram(char board[N][N])
{
		
	int i,j,flag=0,check,size;
	char tempchar,Choice,input_s;

	size=0;
	do
	{
		SW: 
			mainMenu();
			scanf ("%c",&Choice);
			getchar();
			Choice-=48;
			switch (Choice)
			{
				case 0:		//**exit**//
					break;
				case 1:		//**choose board size**//
					do
					{
						if (flag)
						{
							printf("|-incorrect input value-|\n");
						}
						printf("Please choose board size : ");
						scanf("%c",&size);
						getchar();
						size-=48;
						if (size<2 || size>9) flag=1;
						else flag=0;
					}
					while (size<2 || size>9);

					for (i=0;i<=size-1;i++)		// '?' - the board //
					{
						for (j=0;j<=size-1;j++)
						{	
							board[i][j]='?';
						}
					}
					break;
				case 2:						//insert mines//
					if (size!=0)
					{
						input_mines(board,size);
					}
					else
					{
						printf ("you must choose board size first !\n");
					}
					break;
				case 4:
					printBoard(board,size);
					break;
				default: 
					printf("There's no such option\n");
					goto SW;
						 
			}
		}
		while (Choice!=0);
}
int input_mines(char board[N][N],int size)
{
	char temp,mines[40];
	printf ("enter x,y of the new mines (x1,y1)(x2,y2)...(xn,yn):\n");
	scanf ("%s",&mines);
	getchar();
 	insertMine(board,size,mines);
}

void mainMenu()

{
	printf  ("-------------------\n");
	printf  ("welcome to the game\n");
	printf  ("1.Choose board size\n");
	printf  ("2.Place Mines\n");
	printf  ("3.Remove Mines\n");
	printf  ("4.Show mines\n");
	printf  ("5.Start the game\n");
	printf  ("0.Exit\n");
	printf  ("please enter your choice (input controls needed): \n");
}




int insertMine(char board[N][N],int size, char mines[40])
{
	char checking_arr[4],coordinates[160];
	int i,j,k,flag;

	checking_arr[1]='(';
	checking_arr[2]=',';
	checking_arr[3]=')';

	i=0;
	j=0;
	while (mines[i]!=0) //extracting coordinates to var//
	{
		flag=0;
		for (k=1;k<=3;k++)
		{
			do
			{
				i++;
				if (checking_arr[k]==mines[i]) 
				{
					flag++;
				}
				else
				{
					if (48<mines[i]<57)
					{
						coordinates[j]=mines[i];
						j++;
					}
				}
			}
			while (mines[i]==' ');
		}
	}
	if (flag!=3)					//quality check for input//
	{
		printf("wrong input\n");
		for (i=1;i<=160;i++){		//delete the mines[]//
			mines[i]=0;
		}
		mainProgram(board,size);
	}
	else						//all ok ? put the mines into board//
	{
		i=0;
		do
		{
			board[coordinates[i]][coordinates[i+1]]='*';
			i+=2;
		}
		while (coordinates[i]!=0);
	}
}

void printBoard(char board[N][N],int size)

{
	int i,j;
	
	for (i=0;i<=size-1;i++)
	{ 
		printf ("+");
		for (j=0;j<=size-1;j++)
		{
			printf ("-+");
		}
		printf("\n|");
		for (j=0;j<=size-1;j++)
		{
			printf("%s|",board[i][j]);      *?*
		}
		printf ("+");
		for (j=0;j<=size-1;j++)
		{
			printf ("-+");
		}
	}
	printf("\n\n");
}

%c format of the scanf requires pointer to char - you are passing pointer to int - dengerous thing to do

do not use magic numbers, if you want something like
choice-'0' - just write so.

OK, thanks for the tip
Anyone can figure how come my 2d array turning into 1d after calling mainProgram ?

EDIT:

ok nevermind,. the debugger show the array as 1dim though it's just fine.
printf debugging did the trick.
