Answer 1

mati938 Kindly refer this thread to understand segmentation fault.

Edit: Also how can an array already declared with size 10 can take size 11?

Answer 2

because you exceeded the size of the array. n[10][10].
when c or r is greater than 9 it will be out of index range.

Answer 3

segmentation fault occurs when you try to access memory that doesnt exist.

Answer 5

You have problems with indexes starting at zero?
