When we talk about handling errors in programming, especially in university courses like Introduction to Programming, there are some important things to remember. Here are some easy tips to help you understand error handling better:
Before doing anything with inputs, make sure they are what you expect.
For example, if a function is meant to take a whole number (an integer), check that the input is actually a whole number.
This helps avoid mistakes and teaches students the importance of clear rules for their functions.
When something goes wrong, the error messages should be easy to understand.
Instead of just saying "error," it’s better to say something like "Input value is out of range."
This way, users and other programmers can quickly see what happened and how they can fix it.
Teach students to use try-catch tools that are common in most programming languages.
These tools allow programmers to manage problems without causing their program to crash.
It's important to know when to catch these problems and how to deal with them smoothly.
Instead of letting a function fail silently, it’s helpful to return error codes.
A simple return code can show if everything went well or if there was a problem.
For example, returning -1 could indicate that something didn’t work right.
Writing down how errors are handled is very important in programming.
Encourage students to note how they deal with errors in their functions.
This helps them think through their work and gives future programmers a helpful guide when using their code.
Students should practice testing their functions with different inputs, including tricky or incorrect values.
This practice helps them better understand how to handle errors effectively.
By following these tips, students can build strong skills in programming. It shows that handling errors is an important part of creating software, not just an extra task.
