CFD Online Discussion Forums - Problem with declaring an object of a certain class

Hi all,

This is a pretty basic but I need some help. I want to access a member function called GaussNormal() inside the Random class. So I first created a object rnd of class Random.Then called the member function. The following is what I wrote

Code:

Random& rnd;

scalar rn = rnd.GaussNormal();

and I get the following error

Code:

In file included from twoPhaseEulerFoam.C:107:0:

pU/UEqns.H: In function ‘int main(int, char**)’:

pU/UEqns.H:27:13: error: ‘rnd’ declared as reference but not initialized

     Random& rnd;

             ^

pU/UEqns.H:28:33: error: no matching function for call to ‘Foam::Random::GaussNormal()’

     scalar rn = rnd.GaussNormal();

I think I might have to use a constructor, but I don't know how to work that out.
Your help in this matter is greatly appreciated.

Thanks and Regards,
