datamember as reference in a c++ class

[enigmatrix]

I want to use reference variable as a datamember in a c++ class,but during the compilation it is showing an
error: "refence member requires an initializer.."

Program i wrote is:


#include <iostream.h>

extern int pub;
class ex
{
int &data;
public:
ex()
{
data=:ub;
}
};

int pub=200;
void main()
{
ex a;
}
****
Anybody body knows technique to use a reference as datamember.
****

reference members must be initialized in the initialization list, i.e.:

extern int pub;
class ex
{
int &data;
public:
ex():data(pub)
{
}
};

Hope this helps
