In C programming
Declare two 2d arrays n0[MAX_ROW][MAX_COL], n1
[MAX_ROW][MAX_COL].
Then, loop through the 2d array and save the results in n0 and
n1:
for (i=0; i<MAX_ROW; i++)
for (j=0; j<MAX_COL;j++){
//calculate number of
zeros around entry a[i][j]
n0[i][j] =
//calculate number of
ones around entry a[i][j]
n1[i][j] =
}
Set the MAX_ROW and MAX_COL to a small number and display all three 2d arrays on the screen to verify that the calculations are correct. You may still use command-line inputs as in the example program to set the actual size of the array (must be less than or equal to MAX_ROW, MAX_COL.

I am adding the code with the output and i have commented for each condition so that it becomes easy to understand for you...
I have Checked all the possible cases for better and proper outcomes...
if you have any doubt,please ask me in the comment box... please try to understand the logic by making a 2D array on a papper and then see the condition strp by step... it will help you...
