Programs can have syntax errors, logic errors and runtime errors, each needing a different way to find and fix them.
- Syntax: the code is written wrongly
- Logic: the code runs but gives the wrong answer
- Runtime: the program crashes while running

What is Types of Programming Error?
Within Computer Science, which covers algorithms, programming, data, networks, hardware and safe, responsible use of technology, this topic explains Types of Programming Error. Computing topics explain how software, hardware and data work, with diagrams and models that show each step in order.
Check that you can explain Types of Programming Error in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Types of Programming Error helps you design, test and explain programs, websites and systems, from small projects to exam questions.
Types of Programming Error in detail
Syntax errors break the rules of the language, such as a missing bracket or misspelt keyword, and stop the program from running; the translator usually reports them. Runtime errors occur while the program is running, such as dividing by zero or opening a file that does not exist, and cause a crash.
Logic errors are mistakes in the algorithm, so the program runs but gives wrong results, such as using > instead of >=. They are the hardest to find since no message appears, and are found by testing and tracing. Understanding the categories helps you diagnose problems quickly.

Click a card to flip it and reveal the answer, then move on to the next one.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Types of Programming Error.
Real-life uses and examples
- Trace through a process that uses Types of Programming Error to check what it does step by step.
- Recognise Types of Programming Error in an app or device you use every day.
- Apply Types of Programming Error when you design a small program, website or spreadsheet.
Common mistakes to avoid
- Testing only the normal case and forgetting the edge cases.
- Using the term without being able to say what the computer actually does.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
