Write a function in C++ that reverses elements stored in an array.

Note: Actual input array elements are to be swapped i.e. in the below example, swap array element 0 with element 4 and so forth. Temporary array for reversing the elements is NOT allowed.

Sample Output: Enter length of the array: 5 Enter the elements of the array: 11 22 33 44 55 Input array is: 11 22 33 44 55 Reverse of the input array is: 55 44 33 22 11
