What will be logged to the console for the age variable defined as 21?

The age variable defined as 21 is evaluated in the context of conditions that determine the appropriate response based on age. When the age meets or exceeds a certain threshold, such as 21, a particular action or message is triggered. In this case, since the age is 21, it qualifies as being old enough to receive a welcoming message, which is “Thank you. Come on in.”

This reflects that the system is designed to acknowledge ages that meet a certain requirement and respond positively, thus facilitating entry based on age criteria. The logic behind this design is commonly seen in applications that regulate access, such as those dealing with age restrictions for events or services.
