Default initiailizer values are a standard in the C++ language. (I'd quote the C++ reference, but I don't have it handy). I remember using this to also have functions with 'optional' arguments that would be filled in by the default initializers.

Now, while Perl doesn't have this directly, it's very easy to do , particullary if you pass arguments by hash. Damian's OOP has examples like: 

my %func_defaults = ( a=>3, b=>4, c=>5 );

sub func {
    %my_args = ( %func_defaults, @_ );
    ...
}

Or of course, you have friendly operators like ||= (or //= that is in Perl6). It's not as 'simple' as C++ (or C#, apparently)'s default arguments, but they're still there.

I know Java doesn't have this feature, nor C.

It's not what you know, but knowing how to find it if you don't know that's important
