Exercise 3

Consider the following array of integers:

Array of integers, named ‘arr’
2	6	-4	8	10	-12	14	16	18	20
num[0]	num[1]	num[2]	num[3]	num[4]	num[5]	num[6]	num[7]	num[8]	num[9]

 

Implement the following pointer notations to traverse and display the given array ‘arr’.

1.      Printing array using *ptr notation.

2.      Printing array using array[i] notation.

3.      Printing array using ptr[i] notation.

4.      Printing array using *(array+i) notation.

5.      Printing array using *(array+i) notation.

6.      Printing array using *(ptr+i) notation.
