How is multidimensional arrays defined in terms of an array of pointer

1.	How is multidimensional arrays defined in terms of an array of pointer? What does each pointer represent?
Answer» An element in a multidimensional array like two-dimensional array can be represented by pointer expression as follows: ((a+i)+j) It represent the element a[i][j]. The base address of the array a is &a[0][0] and starting at this address, the compiler allocates contiguous space for all the element row-wise. The first element of second row is immediately after last element of first row and so on.

Answer»

An element in a multidimensional array like two-dimensional array can be represented by pointer expression as follows:

*(*(a+i)+j)

It represent the element a[i][j]. The base address of the array a is &a[0][0] and starting at this address, the compiler allocates contiguous space for all the element row-wise. The first element of second row is immediately after last element of first row and so on.
