3. Age Classifier
Write a program that asks the user to enter a person's age. 
The program should display a message indicating whether the person is 
an infant, a child, a teenager, or an adult. Following are the guidelines:
If the person is 1 year old or less, he or she is an infant.
If the person is older than 1 year, but younger than 13 years, he or she 
is a child. 
If the person is at least 13 years old, but less than 20 years old, he or she 
is a teenager. 
If the person is at least 20 years old, he or she is an adult.
