c++:

Write array functions that carry out the following tasks for an array of integers. For each function, provide a test program.

a.Swap the first and last element in an array.

b.Shift all elements by one to the right and move the last element into the first position. For example, 1 4 9 16 25 would be transformed into 25 1 4 9 16.

c.Replace all even elements with 0.

d.Replace each element except the first and last by the larger of its two neighbors.

e.Remove the middle element if the array length is odd, or the middle two elements if the length is even.

f.Move all even elements to the front, otherwise preserving the order of the elements.

g.Return true if all elements of the array are identical.

h.Return the second-largest element in the array.

i.Return true if the array is currently sorted in increasing order.

j.Return true if the array contains two adjacent duplicate values.

k.Return true if the array contains duplicate values (which need not be adjacent).
