Write a program that continues to ask the user to enter any set of numbers, until the user enters the number -1. Then display the total sum of numbers entered and their average. (note that you need to define a counter that counts how many numbers so the average = (sum/n) where n is your counter total.

#include <iostream>

using namespace std;

int main()

{

int number, n=0, sum=0;

cout << "Enter a number to start with " << endl;

cin >> number;

while (number != -1)

{

Answer 1

#include<iostream>
using namespace std;
int main(){
   int number,n=0,sum=0;
   cout<<"Enter a number to start with "<<endl;
   cin>>number;
   while(number!=-1){
       sum=sum+number;
       n=n+1;
       cin>>number;  
   }
   cout<<"sum of numbers: "<<sum<<endl;
   cout<<"Average of numbers: "<<(sum/n)<<endl;
   return 0;
}

Expected output:
