Problem:

Ask the user to enter their age. If they enter non-numeric input, handle the error using try-catch and ask them to enter a valid number.

✅ Valid input:

Enter your age: 20  
You are 20 years old.

❌ Invalid input (letters entered):

Enter your age: hello  
Invalid input! Please enter a valid number.  
Enter your age: 18  
You are 18 years old.
