Add a prototype before main() like: void bubbleSort(Circle [], int); 2. On line 21 add the following function call: bubbleSort(circle, SIZE); 3. After main() function add the definition for bublleSort() function similar to the one on page 628. Evidently you must change the Inventory data type with Circle. The example in the textbook displays all the areas in order because the input is such that will cause the in order output. Your program should display all circles in order even when the input for radii is not in any particular order. // This program uses an array of objects. // The objects are instances of the Circle class. #include <iostream> #include <iomanip> #include "Circle.h" // Circle class declaration file using namespace std; const int NUM_CIRCLES = 4; int main() { Circle circle[NUM_CIRCLES]; // Define an array of Circle objects // Use a loop to initialize the radius of each…In C++: Examine the code segment.
