Using Visual Studio 2015

===============================================================

#include<iostream>
using namespace std;
#include<conio.h>
void main()
{

 int x, num;
 x = 0;
 num = 1;
 while (num <= 100)
 {

  if (num % 2 == 1)
  {

   x = num + x;
   cout << num << " + ";
  }

  num++;
 }

 cout << "\nSum of first 100 odd numbers=" << x;
 _getche();
