The purpose of the program is to take a position and count how many "pixels" are in the "blob". If there is no "pixel" aka the value is 0, the blob number is 0. If there is a pixel, the blob_check function recursively checks the surrounding cells for "pixels" aka values of 1. My program compiles but doesn't accurately count the number of pixels in the blob. Please help!

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

int blob_check(int tab[][], int x, int y);

#define N 5

int main(int argc, char *argv[])
{
int x,y,i,j;
int row=0;

int table[N][N] = { {1,1,0,0,0},
{0,1,1,0,0},
{0,0,1,0,1},

{0,1,0,1,1}};

printf("\t0\t1\t2\t3\t4\t");
printf("\n   -----------------------------------------");
for(i=0;i<5;i++)
{
printf("\n   |\n%d  |\t", i);
for(j=0;j<5;j++)

printf("%d\t", table[i][j]);
}
}

printf("\n\nEnter x-y coordinates of cell  => ");
scanf("%d %d", &x, &y);

printf("Pixel quantity in blob: %i\n", blob_check(table, x, y));

system("pause");
return 0;

int blob_check(int pic[N][N], int x, int y)
{
if (pic[x][y] == 0)
return 0;

pic[x][y] = 0;
