Example Program:

Here is the simple program for printing positive and negative numbers using While Loop in C++.

Source Code

#include<iostream>
using namespace std;
int main()
{
    int i,n,pos=0,neg=0;
    cout<<"\nEnter the starting value:";
    cin>>i;
    cout<<"\nEnter the Ending value:";
    cin>>n;
    cout<<"\nNegative numbers:";
    while(i<=n)
    {
        if(i<0)
        {
            cout<<"\n"<<i;
            neg++;
        }
        i++;
    }
    cout<<"\nPositive numbers:";
    i=0;
    while(i<=n)
    {
        if(i>0)
        {
            cout<<"\n"<<i;
            pos++;
        }
        i++;
    }
    cout<<"\nTotal number of Positive :"<<pos;
    cout<<"\nTotal number of Negative :"<<neg;
    return 0;
