Code:
Im new to C++ programming 
 Im using Visual C++2008.. this is my program.. 


#include "stdafx.h"
#include <iostream>
#include <stdlib.h>


#include <stdio.h>
#include<limits>





void main()
int option =3;
switch (option)
{
case 1:cout<<"one";
	break;
case 2:cout<<"two";
	break;
case 3:cout<< "three";
	break;
default: cout<<"no value";
	system("pause");

}
.... but it doesnt work :( These errors comes... I wanna know why


Error	1	error C2144: syntax error : 'int' should be preceded by ';'	
Error	2	error C2059: syntax error : 'switch'	
Error	3	error C2143: syntax error : missing ';' before '{'	
Error	4	error C2447: '{' : missing function header (old-style formal list?)	


 do I need to include another header file?? please tell me whats wrong :( I have no clue :(
