Forward Range

Question

In the report function, the range.take(5) expression consumes 5 elements. Why isn’t this visibible in the second invokation of report in the main function? Hint: take a look at the signature of take

	`range` is a struct and is therefore passed by copy to `take`	Correct!
	Since `save` is defined on `FibonacciSeries`, it is automaticallly called whenever an argument is passed	`save` is never called automatically
	`range` is `const` so modifications on it are discarded	Modifications of `const` objects is signaled at compile time. Since the program compiles succesfully, `const` is not the problem.
	`report` receives a copy of `range`	`report` specifically receives a reference to `range`
