How is address calculated in an array?
In a single dimensional array the address of an element of an array say A[i] is calculated using the following formula Address of A[i]=B+W∗(i–LB) where B is the base address of the array, W is the size of each element in bytes, i is the subscript of an element whose address is to be found and LB is the Lower limit / …
How is the address calculated in three dimensional arrays?
Formula for 3D Array
- B = Base Address (start address)
- W = Weight (storage size of one element stored in the array)
- R = Row (total number of rows)
- C = Column (total number of columns)
- D = Width (total number of cells depth-wise)
- Ro = Lower Bound of Row.
- Co = Lower Bound of Column.
- Do = Lower Bound of Width.

How do you find the beginning address of an array?
5 Answers
- You declare an array a containing 5 char elements.
- The name of the array ( a ) decays into a pointer to its first element in this context. You add 1 to that and assign the result to ptr . ptr points to the 2 .
- You subtract 1 from ptr and then dereference and print – hence you get the 1 .
Which is the formula for address calculation in row major method?
By Row Major Order If array is declared by a[m][n] where m is the number of rows while n is the number of columns, then address of an element a[i][j] of the array stored in row major order is calculated as, Address(a[i][j]) = B. A. + (i * n + j) * size.
