In this as well as previous implementation of a code of the module(2D arrays section) pointer to pointer has been used.Can you please explain a bit more in detail about this pointer to pointer concept.
Pointer to pointer
@rkganeshan2010
ok so *arr is a pointer pointing to array.
**arr is a pointer which points to pointers of arrays.
Well these things can be bit confusing at times. for learning purpose its fine but in I would advice use vectors.
to declare a vector of size nxm and assign them value c;
vector<vector> v(n,vector(m,c));
