Question

A one dimensional array A has indices 1...75.Each element is a string and takes three memory words .The array is stored at location 1120 decimal .The starting address of A[49] is

a)1267

b)1134

c)1264

d)1169

Answer 1

This is an easy question...:)

Here one assumption to be made.Since word size is not given , we will take default assumption i.e. word size = 1 byte(byte addressable)

Given a[1] address = 1120

So address of a[49] = 1120 + (49 - 1)*3

                             = 1120 + 144

                             = 1264

So C) should be the correct option.
