Question

Consider a 2D array A of 30 (5x6) elements is stored in the memory of 120 bytes from 2100 to 2216. Find out the address of A[2][4] element in row-major and column-major order.

Answer 1

3rd row, 5th element

24 bytes per row

so 3rd row is 72 bytes offset

so 4rd row begins at 2172

the row major address is 2188
