c++ Programming -11a -do/while

In this programming, we will cover everything we have cover in our c++ programming including switch case, if/else, gotoxy coordination, do/while and system clear
First, code for the header file stdafx.h:

// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//

#pragma once


#include

using namespace std;

// TODO: reference additional headers your program requires here

Name the main file anyhow you like.
Programming codes for the main file below:

// IntAirways.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
