Question

$\text{A is an array}$$[5\cdots 15,-5\cdots 5]$ $\text{of elements.}$ $\text{The starting location is 100.}$ $\text{Each element occupies 4 memory cells.}$ $\text{Calculate the location of an element}$ $A(6,2)$ $\text{using column major order.}$

• A. 612
• B. 412
• C. 400
• D. 512

Answer 1

The correct option is B 412

option (d)

$\left[\begin{array}{c}{b}_1{u}_1{b}_2{u}_2\\ 5\cdots 15,-5\cdots 5\end{array}\right]L_0=100,\text{CMO:}locA[i,j]=L_0+\left[\right(j-b_2\left)\right(u_1-b_1+1)+(i-b_1)\ast CA(6,2)=100+[(2-(-5\left)\right)(15-5+1)+(6-5)]\ast 4=100+[\left(7\right)\left(11\right)+1]\times 4=100+312=412$
