Error Types Formula
The Formula
When to use: Some bugs stop the code from running, some crash it later, and some quietly give the wrong answer.
Quick Example
What This Formula Means
Error types are the main categories of mistakes that can occur in a program. The most common categories are syntax errors (the code is written incorrectly), runtime errors (the program crashes while running), and logic errors (the program runs but gives the wrong answer).
Some bugs stop the code from running, some crash it later, and some quietly give the wrong answer.
Formal View
Common Mistakes
- Calling every wrong answer a syntax problem even when the code runs
- Fixing one runtime crash without checking whether a deeper logic problem remains
- Ignoring compiler or interpreter messages that already identify the error category
Common Mistakes Guide
If this formula feels simple in isolation but keeps breaking during real problems, review the most common errors before you practice again.
Why This Formula Matters
Students debug faster when they can name the kind of error they are dealing with. Error types give structure to debugging instead of treating all bugs as the same.
Frequently Asked Questions

How do you use the Error Types formula?

Why is the Error Types formula important in CS Thinking?
Students debug faster when they can name the kind of error they are dealing with. Error types give structure to debugging instead of treating all bugs as the same.
What do students get wrong about Error Types?
Logic errors are often the hardest because the program still runs, so the bug is less obvious.
What should I learn before the Error Types formula?
Before studying the Error Types formula, you should understand: debugging.
