@Rizwan: Not completely. What if ROW in your code is a variable (not a
constant) that is not known until run time? Then you need to
dynamically allocate space for your arr2D as well. So, contradicting
my earlier "No" response, maybe something like this would work to
allocate an array a with m rows and n columns:
int* a = (int*)malloc( m * ( sizeof(int*) + n * sizeof(int) ) );
for( i = 0 ; i < m ; ++i )
a[i] = a + m + i * n;
