Explanation: In the above program, *arrp[3] is declared as an array of pointers. Using first

for loop, the addresses of various elements of array ‘arr[]’ are assigned to ‘*arrp[]’.

The second for loop picks up addresses from ‘*arrp[]’ and displays the values present at

those locations. Here, each element of ‘*arrp[]’ points to the respective element of array

‘arr[]’.
