How do I put a language changer in the header of Magento 2?

Every store owner has multiple customers in many countries which are different from each other by language and currency.

The Magento 2 Multi-Country language Popup gives that feature to the admin to give the advantage of the country language popup option. As it helps the customer to explore the website in their language and currency will also change according to the store view and country selection

The Language Switcher is a built-in Magento feature. Store views created in the admin panel are displayed in the store switcher on the storefront as shown below image.
