#include <iostream>

using namespace std;

int main()

Here is how you create a Windows GUI app.

#include <windows.h>
#include <tchar.h>
#include <crtdbg.h>

LRESULT CALLBACK WndProc (HWND hwnd, unsigned int msg, WPARAM wParam, LPARAM lParam)
{
  switch (msg)
  {
    case WM_CREATE:
    {
      HINSTANCE hIns = ((LPCREATESTRUCT)lParam)->hInstance;
      return 0;
    }
    case WM_COMMAND:
    {
      return 0;
    }
    case WM_DESTROY:
    {
      PostQuitMessage (0);
      return 0;
    }
  }

  return (DefWindowProc (hwnd, msg, wParam, lParam));
}


int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevIns, LPSTR lpszArgument, int iShow)
{
  TCHAR szClassName[] = _T("Template");
  TCHAR szWindowName[] = _T("Template");
  WNDCLASSEX wc = { 0 };
  MSG messages;
  HWND hWnd;

  wc.lpszClassName = szClassName;
  wc.lpfnWndProc = WndProc;
  wc.cbSize = sizeof (WNDCLASSEX);
  wc.hbrBackground = (HBRUSH)COLOR_BTNSHADOW;
  wc.hInstance = hInstance;
  
  _ASSERTE(RegisterClassEx (&wc) !=0);
  
  hWnd = CreateWindowEx (0, szClassName, szWindowName, WS_OVERLAPPEDWINDOW, 
      CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, 
      HWND_DESKTOP, 0, hInstance, 0);
      
  _ASSERTE(::IsWindow(hWnd));
  
  ShowWindow (hWnd, iShow);
  while (GetMessage (&messages, NULL, 0, 0))
  {
    TranslateMessage (&messages);
    DispatchMessage (&messages);
  }

  return static_cast<int>(messages.wParam);
}
