Initializing a reference within a structure

How does one initialize a reference within a structure?

Example:

Code:

struct _s {
  char& c;
}

The reference must be initialized when you instantiate the struct. I believe in that case you've shown, you'd have to create a constructor for the struct that initialized the reference to something. There may be a problem with multiple instances of the struct as they might have all there c data members initialized to the same value (You'd have to check that out yourself).

So I might as well use a class. Thanks.

struct or class, it doesn't really matter that much, structs can have constructors and member functions just like classes do.
