[A J]

I have a situation like this:


A.h looks something like:


struct B:C{
   size_t x;
   D *e();

   gsl_vector *g;
}

class A{
..............
   C *f;
   size_t xa;
   C *h;
.............

}



Now, inside of A.cpp has as method that looks like:

D *B::e(){

}


I want to use g inside this method, but I don't necessarily want to allocate
and deallocate it everytime this method is called. I would like to allocate
it exactly once, if possible in the constructor A::A() itself.

Can Anyone help me figure this out?

Thanks,
A
