Using multiple files in C++

[csripriya1]

Hi I am having trouble in programming using multiple files in C++.
I have a class declaration in a header file like this.
class test
{
private:
data;
public:
void testfunc();
}

I included this header in a source file, which gives the definition for those functions in the class in header file.

#include "blahblah.h"

void test::testfunc()
{
.......
}

I am calling a function of this class from main . So, I included this header file in main too.

#include <iostream.h>
#include &quot;blahblah.h&quot;

void main()
{
test justfortest;
.............


justfortest.testfunc();

}
When I am trying to compile this , compiler complains about the functions being declared twice.can anyone pl help me with this.
Thanks for your time.
I posted this in unix forum too.am sorry for that

try this

#ifndef testlib
#define testlib
//your code here
#endif

That way your class definition will only be processed once
