Types of errors

• What is the primary purpose of testing in computer programming?

  Verify functionality
• Testing helps detect and fix bugs before release


  True
• One benefit of testing is to verify that the software performs as intended
• What is one critical failure that testing can prevent in software development?

  Production failures
• Functional requirements define the core functionality and capabilities
• What type of error occurs when code violates the grammar of the programming language?

  Syntax error
• Logic errors can cause unexpected program behavior without crashing the system


  True
• Runtime errors can cause a program to crash
• What does testing software verify functionality of?

  The software performs as intended
• What is improved when software is tested thoroughly?

  Reliability and maintainability
• Functional requirements describe what the system should do
• Non-functional requirements describe how the system should perform.


  True
• What do functional requirements define about a system?

  What the system should do
• Non-functional requirements focus on quality attributes, constraints, and other criteria
• What are examples of functional requirements?

  Login, search, add to cart
• Misspelled keywords can cause syntax errors.


  True
• Division by zero is a common cause of runtime errors.


  True
• Logical errors occur when the program produces incorrect results
• What is an example of a syntax error in Python?

  `prin("Hello world")`
• Match the requirement type with its description:

  Functional ↔️ Describes what the system should do

  Non-Functional ↔️ Describes how the system should perform
• Non-functional requirements focus on quality attributes like response time and security


  True
• A common cause of syntax errors is a missing parenthesis
• What is one common cause of runtime errors in computer programs?

  Division by zero
• Match the error type with its example:

  Syntax ↔️ `prin("Hello world")`

  Logic ↔️ `x + y` instead of `x - y`

  Runtime ↔️ `int z = 10 / 0`
• Testing helps to identify and fix bugs
• Testing prevents failures in the production environment.


  True
• What do functional requirements define about a system?

  Core functionality and capabilities
• Match the type of requirement with its description:

  Functional ↔️ Describes what the system should do

  Non-Functional ↔️ Describes how the system should perform
• Functional requirements define the core functionality of the system.


  True
• Non-functional requirements include response time, security, and scalability
• What causes syntax errors in code?

  Violation of language grammar
• Match the type of error with its definition:

  Syntax ↔️ Violation of language grammar

  Logic ↔️ Code produces unexpected results

  Runtime ↔️ Errors during program execution
• Runtime errors occur when the program performs an illegal or impossible operation
• What happens when a runtime error occurs?

  The program crashes
• Incorrect comparisons are a common cause of logical errors.


  True
• What is an example of a logical error in Python?

  `x + y` instead of `x - y`
