BELOW IS A CODE SNIPPET

#include <iostream> // Necessary for COUT and CIN
#include <string> //Necessary for STRING variables
#include <mmsystem.h>   //Necessary for PlaySound
#include <windows.h>    //Necessary for HANDLE,      
                    //  BACKGROUND_ and FOREGROUND_ consts, Beep
 using namespace std; // Using the standard naming conventions

#pragma comment(lib, "winmm.lib")



int main()
{

//PlaySound(TEXT("allnighter.wav"), 0, SND_SYNC);

the program gives me many errors as soon as i try to run the program with #mmsystem.h

Assume that I have closing brackets at the end of my main, again this is only a snippet, my program works fine without including mmsystem.h
