Final answer:

To prevent program crashes due to invalid inputs, use try-except blocks to handle non-numeric entries.


Explanation:

When checking for an invalid input number in a program, you can utilize try-except blocks to handle non-numeric inputs gracefully. By using a try block to attempt to convert the input to a number, you can catch errors using an except block and print a message to the user, preventing the program from crashing.

As an example, in Python:

  1. try:
  2.  number = int(input('Enter a number: '))
  3. except ValueError:
  4.  print('Invalid input. Please enter a valid number.')

This approach ensures that the program handles invalid inputs gracefully without crashing.
