Write a well documented C++ program consisting of the following to functions Write a function that accepts an array of integer elements and to size as parameters, swaps the two halves of the way as shown below if the attay contains the following 5 9 2 12 8 4 Then your function should swap the two halves of the given array so as it becomes as follows 12 8 4 5 9 2 Write a function main that defines an array consisting of 13 integer elements and performs the following tasks in order . fills the array by prompting the user to enter 13 integer values from the keyboard: displays al array elements separated by two spaces swaps the two halves of the array by calling the above defined function displays all array elements (after swapping) separated by tabs Hints 1 Develop and check the correctness of the tasks in a and parts before starting parts and d 2 Try and practice the following program structures your program write the main() function after the first function your program wiite the first function after the main function. You have to use the prototype in this case
