What is the address of element (19, 25) of a150 by 200 array of words whose base address is 0x1004 52C4D? (Show your work)

If it is a row major array?

Solution

Given 2d array of size 150x200
So every row it has 150 elements.
so 19th row meand it has already passed 18 rows ==> (18x150 ==> 2700)
Then 25th column means ==> 2700+25 ==> 2725 element.

0x1004 52C4D ==> 4100 (decimal)
So 4100 + 2725 ==> 6825 (decimal)
6825 (decimal) ==> 1AA9 (hexadecimal)
