Write a well-documented C++ program consisting of the following two functions. Write a function that accepts an array of double elements and its size as parameters, swaps the two halves of the array as shown below. If the array consists of 7 elements as follows: 5 9 99 12 8 4 Then your function should swap the two halves of the given array so as it becomes as follows: 12 8 4 99 5 9 2 Write a function main () that defines an array consisting of 15 double elements and performs the following tasks in order: a) fills the array by prompting the user to enter 15 double values from the keyboard; b) displays all array elements (before swapping) separated by two spaces; c) swaps the two halves of the array by calling the above-defined function3B d) displays all array elements (after swapping) separated by tabs.
