constant variable, local and passing to methods

[puzzlecracker]

How can I pass a reference to a method as constant?

I tried the following:

Function(const Foo f) or Function(readonly Foo f)


Also, How to declare local variable to be constant

const Foo foo or readonlyFoo f?

 

[puzzlecracker]

void Function(Foo const & f);





Foo const f;

argh, again sent it to the wrong group.. IHMO
