Refining algorithms to make them more robust

Question 1

What is the goal of refining algorithms to make them more robust?

Answer 1

To write code that anticipates a range of possible inputs

Question 2

What should you consider when refining algorithms for robustness regarding user inputs?

Answer 2

Ensure prompts for the user are descriptive and helpful

Question 3

What is one common way to handle errors in programming languages?

Answer 3

Using simple exception handling commands.

Question 4

What is a potential issue with forcing users to input certain data types?

Answer 4

The program may crash if anything other than the expected data type (e.g.

Question 5

How can you improve user feedback when invalid data is entered?

Answer 5

By making the prompt to the user more descriptive and helpful.

Question 6

How can you prevent a program from crashing when invalid data is entered?

Answer 6

By using error-catching code

Question 7

What is exception handling in programming?

Answer 7

A mechanism where you “try” a line of code

Question 8

Why is it important to check for missing or blank data when refining algorithms?

Answer 8

To ensure the program can handle incomplete or absent inputs without crashing or producing incorrect results.

Question 9

What are two ways to make user prompts more effective?

Answer 9

1) Make them descriptive and helpful. 2) Ensure they guide the user to enter data of the correct type.

Question 10

What does it mean to “catch” an error in exception handling?

Answer 10

It means to intercept an error that occurs during the execution of code and handle it gracefully

Question 11

What is the purpose of the “try” block in exception handling?

Answer 11

To execute a block of code that might generate an error

Question 12

What happens if an error occurs in the “try” block and is not caught?

Answer 12

The program will crash or terminate unexpectedly.

Question 13

What is the role of the “except” block in exception handling?

Answer 13

To specify the code that should run if an error occurs in the “try” block

Question 14

Why is anticipating a range of possible inputs important for robust algorithms?

Answer 14

It ensures the program can handle unexpected or invalid inputs without failing or producing incorrect results.

Question 15

What is one example of invalid or erroneous data that algorithms should anticipate?

Answer 15

Data of the wrong type (e.g.
