Trouble with 2d arrays

[FattyMcPants]

So I'm taking a matrix from a file.
5 6
R F F F F F
F F F F F F
R R R F F F
F F F F F F
F F F F F F

And put it in to a 2d matrix called arr and convert Rs to 0 and Fs to 1.
d1 is the number of rows, d2 is the number of columns
for(int i = 0; i < d1; i++)
{
for(int j = 0; j < d2; j++)
{
int binary = 0;
input >> let;

if(let == 'F')
binary = 1;

arr[i][j] = binary;
}
}

I create a new array S from the previous array filling in first the first row then the first column
for(i = 0; i < d1; i++)
{
S[i][0] = arr[i][0];
}

for(j = 0; j < d2; j++)
{
S[0][j] = arr[0][j];
}

This works fine but the next part is where the error lies
//calculate the rest of the table
for(i = 1; i < d1; i++)
{
for(j = 1; j < d2; j++)
{
if(arr[i][j] == 1)
{
S[i][j] = min(S[i][j-1], S[i-1][j], S[i-1][j-1]) + 1;
}
else
S[i][j] == 0;

cout << S[i][j] << " ";
}
cout << endl;
}

so my output looks like
0 1 1 1 1 1
1 1 2 2 2 2
0 0 -1081966312 -1081966311 -1081966310 -1081966309
1 1 -1081966311 -1081966311 -1081966310 -1081966309
1 2 -1081966310 -1081966310 -1081966310 -1081966309

Can anyone help me figure out why it gives me those weird numbers? Any help is appreciated.
The min function is
int min(int a, int b, int c)
{
int m = a;
if(m > b)
m = b;
if(m > c)
m = c;
return m;
}
just for reference.

Thanks in Advanced

I think this will solve the problem

for(i = 1; i < d1; i++)
{
	for(j = 1; j < d2; j++)
	{
		if(arr[i][j] == 1)
		{
			S[i][j] = min(a[i][j-1], a[i-1][j], a[i-1][j-1]) + 1;
		}
		else 
			S[i][j] == 0;
	}
}
