In this lab, you complete a C++ program that uses an array to store data for the village of Marengo. The program is described in Chapter 8, Exercise 5, in Programming Logic and Design. The program should allow the user to enter each household size and determine the mean and median household size in Marengo. The program should output the mean and median household size in Marengo. The file provided for this lab contains the necessary variable declarations and input statements. You need to write the code that sorts the household sizes in ascending order using a bubble sort and then prints the mean and median household size in Marengo. Comments in the code tell you where to write your statements.1. Open the source code file named HouseholdSize. cpp using Notepad or the text editor of your choice.2. Write the bubble sort.3. Output the mean and median household size in Marengo.4. Save this source code file in a directory of your choice, and then make that directory your working directory.5. Compile the source code file HouseholdSize. cpp.6. Execute the program with the following input and record the output: Household sizes: 4, 1, 2, 4, 3, 3, 2, 2, 2, 4, 5, 6Here is the Householdsize. cpp file information:// HouseholdSize. cpp - This program uses a bubble sort to arrange up to 300 household sizes in// descending order and then prints the mean and median household size.// Input: Interactive.// Output: Mean and median household size.#include #include using namespace std;int main(){ // Declare variables. const int SIZE = 300; // Number of household sizes int householdSizes[SIZE]; // Array used to store 300 household sizes int x; int limit = SIZE; int householdSize = 0; int pairsToCompare; bool switchOccurred; int temp; double sum = 0; double mean = 0; int medianIndex = 0; // Input household size cout << "Enter household size or 999 to quit: "; cin >> householdSize; // Fill an array with household sizes - the maximum households = 300 x = 0; while(x < limit && householdSize != 999) { // Place value in array. householdSizes[x] = householdSize; // Calculate total of household sizes using the sum variable x++; // Get ready for next input item. cout << "Enter household size or 999 to quit: "; cin >> householdSize; } // End of input loop. // set the limit to x // calulate the mean household size by dividing the sum by the limit // Use one of your sort routines to sort the Array so that the house sizes are in ascending order // Print the mean // Set medianIndex = (limit-1)/2 // Print the median found at householdSizes[medianIndex] return 0;} // End of main function
