C++ 20 (2a) New Features - Using Ranges

The video tutorial introduces the concepts of range generators and adapters. Range generators are functions that create ranges of values, computed lazily, allowing for infinite sequences. Examples include iota, single, empty, and counted. Range adapters modify existing ranges without altering the original container, using composable steps. Examples include all, filter, transform, reverse, take, join, split, and common. The video sets the stage for further examples in the next session.

What is the primary characteristic of a range generator?

• It modifies the original container.

• It creates a new range of values lazily.

• It filters elements based on a condition.

• It reverses the order of elements.

Which function creates an infinite range of values?

• Empty

• Iota

• Counted

• Single

How do range adapters modify a range?

• By creating a new container

• By deleting elements

• By applying composable steps

• By changing the original container

Which adapter would you use to create a view with only elements that satisfy a certain condition?

• Join

• Filter

• Transform

• Reverse

What is the purpose of the 'common' adapter?

• To reverse the order of elements

• To interface with legacy code

• To flatten a range of ranges

• To split a range into sub-ranges
