Explain how dynamic memory can be allocated to twodimensional array when the dimensions are not known at compile time. [Hint: Use pointer to pointer concept.]

The declarations int a[5][6] ans *a [6] and **a all refer to the same two-dimensional array of integers. Explain the process of memory allocation for the above three declarations.
