Challenge: if, else-if, else

Write a program that reads an integer age from the user and prints the user's category based on the following rules:

• If the age is less than 18, print "child";
• If the age is 18 or older but less than 65, print "adult";
• If the age is 65 or older, print "senior".

Use if, else if, and else statements to implement this logic. Only print the category name ("child", "adult", or "senior").
