6.3.2 Identifying and correcting errors:

• What are the two distinct types of errors in programming?

  Syntax errors and logic errors
• Syntax errors and logic errors are two distinct types of errors that can occur in programming
• Unit testing is implemented for error prevention
• Match the type of error with its description:

  Syntax Error ↔️ Error in the grammar of the code

  Logic Error ↔️ Error in the program's algorithm
• Syntax errors are detected by the compiler
• Match the compiler message with its description:

  Missing Semicolon ↔️ Statement lacks an ending semicolon

  Undeclared Variable ↔️ Variable used without definition

  Type Mismatch ↔️ Value of one type assigned to another

  Invalid Operator ↔️ Unsupported operator used
• An undeclared variable error means the variable was not defined before use.


  True
• What is an example of a logic error when calculating the area of a rectangle?

  Using width + height
• What are compiler messages used for?

  Identify syntax errors
• Print statements help trace the program's execution to identify logic errors.


  True
• Compare debugging tools and print statements based on their features:

  1️⃣ Debugging tools allow real-time variable inspection

  2️⃣ Debugging tools provide code stepping

  3️⃣ Debugging tools offer full control over execution flow

  4️⃣ Print statements require manual insertion and removal

  5️⃣ Print statements can clutter code and slow execution
• Syntax errors are errors in the structure or grammar of the code
• Syntax errors stop the program from running.

  True
• Who detects logic errors in programming?

  Not compiler or interpreter
• Compiler messages inform developers about syntax errors
• What does an undeclared variable error refer to?

  Using a variable not defined
• What does an invalid operator error indicate?

  Using an unsupported operator
• Print statements require manual insertion and removal for variable tracking.


  True
• Print statements provide full control over the program's execution flow.

  False
• What is a key advantage of debugging tools over print statements for variable tracking?

  Real-time inspection
• Match the error type with its example:

  Syntax Error ↔️ `int x = 5` (missing semicolon)

  Logic Error ↔️ Calculating area using `width + height`
• What type of errors are unit tests particularly effective at catching?

  Syntax errors
• Online debugging resources include documentation and online forums
• The official documentation for a programming language can explain its syntax
• Online forums like Stack Overflow allow developers to post code and receive help from experienced developers
• What is the primary difference between syntax errors and logic errors?

  Structure vs algorithm
• Logic errors are detected by the compiler or interpreter.

  False
• Why do syntax errors prevent a program from running?

  Violate code structure
• Compiler messages help identify errors that prevent a program from compiling.


  True
• What does a compiler message indicating an undeclared variable mean?

  Variable not defined
• Print statements are more efficient than debugging tools for complex logic errors.

  False
• Order the steps to debug logic errors using debugging tools:

  1️⃣ Set a breakpoint

  2️⃣ Run the program

  3️⃣ Step through the code

  4️⃣ Inspect variable values

  5️⃣ Modify code as needed
• Debugging tools allow monitoring variable changes in loops more effectively than print statements.


  True
• A missing semicolon in code is an example of a syntax error.
• What type of error occurs when calculating the area of a rectangle using `width + height` instead of `width * height`?

  Logic Error
• Syntax errors prevent the program from compiling or running.


  True
• Unit tests are effective at catching syntax errors because they will fail to run
• Unit tests can uncover logic errors by validating expected program behavior.


  True
• Compiler documentation provides guidance on common syntax errors
• Breaking a program into smaller modules makes it easier to debug.
