Write a program that continues to read positive integer values until user enters a negative value. the program should print average of entered values, maximum value and minimum value

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

int main()

{

// variable

   int n;

   int mi=INT_MAX;

   int mx=INT_MIN;

   double avg;

   int count=0;

   double sum=0;

   cout<<"enter a positive integer(Negative number to stop):";

   // read the input first time

   cin>>n;

   // read the input until user enter a negative number

   while(n>=0)

   {

   // calculate minimum

       if(n<mi)

       mi=n;

       // calculate maximum

       if(n>mx)

       mx=n;

       // count of entered numbers

       count++;

       // total sum of all number

       sum=sum+n;

       cout<<"enter a positive integer(Negative number to stop):";

       // read the input again

       cin>>n;

   }

   // calculate the average

   avg=sum/count;

   // print the average

   cout<<"average of "<<count<<" number is:"<<avg<<endl;

   // print the maximum

   cout<<"maximum of all number is:"<<mx<<endl;

   // print the minimum

   cout<<"minimum of all number is:"<<mi<<endl;

return 0;

}

Explanation:

Declare and initialize "mi" with maximum integer value.Similarly "mx" with minimum integer value.Read user input until user enter a negative number.Add all the number to variable "sum" and keep count of positive number entered with "count".When user enter a negative number then it will stop taking input and calculate average of all number by dividing sum with count. Also it will check for each and find the maximum and minimum among the all input.

Output:

enter a positive integer(Negative number to stop):23

enter a positive integer(Negative number to stop):10

enter a positive integer(Negative number to stop):34

enter a positive integer(Negative number to stop):22

enter a positive integer(Negative number to stop):5

enter a positive integer(Negative number to stop):-2

average of 5 number is:18.8

maximum of all number is:34

minimum of all number is:5
