Answer to Question #290182 in C++ for S bharath

Question

Create a class called numbers which should hold 10 integer numbers in an array. The array should be private. Now include the following member functions in the class (in addition to any other function that you may deem necessary): (a) sum() which will find the sum of the member elements. (b) average() which will find the average (c) max() which returns the maximum value (d) sort_desc() which will sort the array in descending order.

Answer 1

#include<conio.h>
#include<stdio.h>
#include<stdlib.h>
#include <iostream>
