Hello @sid.rajput23 this is the concept of 2d matrix which we are forming dynamically.
and it is happening like in line this depicts a pointer to the pointer.
and when we are coming one very index then for that particular row we are dynamically forming 1d array at that index of the array.
that means if we at the 0th index then at the 0th index we have dynamically allocated one 2d array.
if you still have doubt in any line you can ask here:
Happy Learning!!
