Weird output loop+array.

I've got the following function:

Code:

void deck()
{
	int cards[14][4];
	int a;
	int b;
	for (b = 0; b < 4;b++)
	{
		for (a = 1; a < 15; a++)
		{
			cards[a][b] = a;
			printf("%d\n",cards[a][b]);
		}
	}
return;
}

The output is:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
1

I notice it sort of crashes in the 3rd time it does the b loop. At least it puts a silly value in cards[14][3]
and then stops doing the loop.

Could anybody help?

Thank You.

Recall that array indices start from 0.

Code:

int cards[14][4];

Valid indicies for the first dimension are from 0 through 13 (inclusive). You are going from 1 to 14.
