I have a C++ Compiling error and cant figure out what it is can you help me?

ok I'm using the Irrlicht engine and im using Dev-C++ these are my #includes:





#include %26lt;irrlicht.h%26gt;


#include %26lt;IEventReceiver.h%26gt;


#include "Keycodes.h"


#include %26lt;stdio.h%26gt;


#include "CMainMenu.h"


#include %26lt;cstdlib%26gt;


#include %26lt;iostream%26gt;


#include %26lt;istream%26gt;


#include %26lt;ostream%26gt;


#include %26lt;fstream%26gt;


#include %26lt;iomanip%26gt;





and theese namespaces:


using namespace std;


using namespace irr;


using namespace core;


using namespace scene;


using namespace video;


using namespace io;


using namespace gui;


using namespace std;





now in my program i have ths function:





int edit(int a, int b)


{


core::vector3df v = camera-%26gt;getPosition();


ofstream myFile("test.txt");


myFile %26lt;%26lt; v;


myFile.close();


}





now when i try to compile this program it gives me this error





no match for 'operator%26lt;%26lt;' in 'myFile %26lt;%26lt; v'





and i cant figure out what is wrong with this i have all the includes and namespaces PLEASE HELP





thanks in advanced

I have a C++ Compiling error and cant figure out what it is can you help me?
Just check the following code written by you...





Line1: int edit(int a, int b)


Line2: {


Line3: core::vector3df v = camera-%26gt;getPosition();


Line4: ofstream myFile("test.txt");


Line5: myFile %26lt;%26lt; v;


Line6: myFile.close();


Line7: }





In line 3 you are declaring a variable "v" of type "core::vector3df".


In line5 you are trying to write the contents of "v" to myFile.


Here you are getting error.


This is because of the fact, that "%26lt;%26lt;" and "%26gt;%26gt;" overloaded operators are defined only for the built in types and not for the userdefined class objects..


But you are trying to use "%26lt;%26lt;" operator for an object of user defined class...In case you want to do this, first of all, you have to write code to overload the "%26lt;%26lt;" operator in your class definition.


Only then it will work...


Other part of the code is okay..

Reply:I'm not an expert on C++ so some of the questions I might be asking you might just be a total waste of your time so I apologize in advance.





According to the error statement, you might want to check if you have a file named test.txt in the same directory and what is in it.





The fourth line in your program starts with "ofstream". You have #include's for "fstream" and "ostream" and I'm thinking this may just be a typo.
