Question

Using basic c++

2. Count the positive and negative numbers using ***while loop***

• Write a program that reads unspecified number of integers , determines how many negative and positive values have been read. Also calculate total and average. Your program will end with input 0.

• Output

Enter an integer, the input ends if it is 0: 25 34 -89 72 -35 -67 21 48 0

The number of positives is 5

The number of negatives is 3

The total is 9

The average is 1.125

Answer 1

#include <iostream>
using namespace std;

int main(){
   int n, positive = 0, negative = 0, total = 0, count = 0;
   cout<<"Enter an integer, the input ends if it is 0: ";
   cin>>n;
   while(n!=0){
      if(n>0){
         positive+=1;
      }
      else{
         negative += 1;
      }
      total+= n;
      count += 1;
      cin>>n;
   }
   cout<<"The number of positives is "<<positive<<endl;
   cout<<"The number of negatives is "<<negative<<endl;
   cout<<"The total is "<<total<<endl;
   cout<<"The average is "<<(total*1.0/count)<<endl;
   return 0;
