📚 Topic Summary
Debugging is the process of identifying and fixing errors (bugs) in computer code. It's a crucial part of software development. Debugging techniques include carefully examining code, testing different inputs, and using tools to step through the code's execution. Mastering these techniques will save you time and frustration as you write more complex programs. This worksheet focuses on applying debugging techniques within the context of the AP Computer Science Principles (CSP) curriculum.
🧠 Part A: Vocabulary
Match each term with its correct definition:
| Term |
Definition |
| 1. Syntax Error |
A. A problem that occurs when the program attempts an invalid operation, like dividing by zero. |
| 2. Logic Error |
B. An error that prevents the program from running because of incorrect code structure. |
| 3. Runtime Error |
C. An error where the program runs, but does not produce the intended result. |
| 4. Debugger |
D. A tool used to step through code and examine variables. |
| 5. Test Case |
E. A specific set of inputs and expected outputs used to verify program correctness. |
Match the term to the definition: 1 - __, 2 - __, 3 - __, 4 - __, 5 - __
✏️ Part B: Fill in the Blanks
Complete the following paragraph using the words provided below:
When debugging, it's helpful to use a systematic approach. First, try to ________ the problem. Next, formulate a ________ about the cause. Then, ________ your hypothesis by testing your code with different ________. If the ________ fail, revise your hypothesis and try again. Using a ________ can help you step through your code line by line.
Word Bank: reproduce, debugger, test cases, hypothesis, tests
🤔 Part C: Critical Thinking
Imagine you have written a program that is supposed to calculate the average of a list of numbers. However, when you run the program, it always outputs a value that is much larger than expected. Describe the steps you would take to debug this program. Be specific about the debugging techniques you would use.
