Question

Suppose there is an integer array m[4,5], address of m[0,0] is 1000, and m[0,3] is 1006. The address of m[3,4] is?

the answer is given as 1038

 

what is wrong in my approach?

1000+2((3x6)+4)= 1044

Comments

1000 + 2((3 * 5) + 4) should be the calculation.

but there are 6 columns right?

---

m[4,5] - 4 rows, 5 columns

---

We consider previous rows and columns

So 4-0= 4

And 5-0 =5

Note: don't consider current rows and columns
