Question

C++ PROGRAMING

Write a program that reads numbers from the input stream until a zero is encountered. Display the average (rounded down to an integer), the maximum number and the minimum number. Assume that numbers entered will be between 1 and 1000. For example:

Enter a number: 33

Enter a number: 88

Enter a number: 77

Enter a number: 22

Enter a number: 66

Enter a number: 55

Enter a number: 0

Average: 56

Max: 88

Min: 22

Another example:

Enter a number: 0

No data, so no answers!

Run it 5 times with different data, including the two above examples.

Answer 1

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{

//Declaring variables.
   int value,sum=0,average,count=0,min=0,max=0;
  
   //Getting the number from the user.
   cout<<"Enter a Number :";
   cin>>value;
  
   //Assinging the value to min and max variables
   min=value;
   max=value;
  
   /* Checking whether the value is zero or not
   * If zero Display the message and exit the program.
   */
   if(value!=0)
   {
       do
       {
           /* For every valid input(Entered Number other than zero)
           * increment the count value by 1
           */
           count++;
          
           //Calculating the sum
           sum+=value;
          
           //Getting the number entered by the user
           cout<<"Enter a Number :";
           cin>>value;
          
           //calculating the maximum and minimum values
           if(value!=0)
           {
           if(value>max)
       max=value;
       if(value<min)
       min=value;
           }
                  
       }while(value!=0);//this loop repeats until user enters Zero.
   }
   else
   {
       //Displaying the error message
       cout<<"** NO data so no answers **"<<endl;
       exit(0);
   }
  
   //Calculating the average
   average=sum/count;
  
   //Displaying the average
   cout<<"Average :"<<average<<endl;
  
   //Displaying the maximum number
   cout<<"Max :"<<max<<endl;
  
   //Displaying the minimum number
   cout<<"Min :"<<min<<endl;
return 0;
}
