Types of errors

• What is the purpose of testing in software development?

  Identify and fix errors
• Syntax errors differ from semantic errors in the type of error
• Order the types of errors from those identified first to those identified last during testing.

  1️⃣ Syntax errors

  2️⃣ Logic errors

  3️⃣ Runtime errors
• Runtime errors occur during the execution of the program.


  True
• What is a common cause of runtime errors during program execution?

  Out-of-bounds array access
• What is an example of a logic error that can cause an infinite loop?

  Incorrect condition
• Logic errors occur due to flaws in the algorithm or logic
• Runtime errors occur while the program is running due to unexpected inputs or environmental conditions.


  True
• Why is testing crucial for developing robust programs?

  Ensures program reliability
• Logic errors occur when the program produces unexpected results due to flawed algorithms or incorrect reasoning
• What is an example of a runtime error that occurs during program execution?

  Dividing by zero
• What are the main types of errors in software development?

  Syntax, logic, runtime
• Provide an example of a runtime error.

  Division by zero
• What is the primary result of a logic error in a program?

  Incorrect output
• Syntax errors prevent the program from compiling
• Syntax errors are errors in the structure or grammar
• Who typically detects syntax errors in software development?

  Compiler or interpreter
• What type of error occurs when the code is syntactically correct but produces incorrect results due to flaws in the algorithm or logic used?

  Logic Errors
• Steps involved in the testing process to ensure software functions correctly:

  1️⃣ Identify errors or bugs

  2️⃣ Fix errors or bugs

  3️⃣ Retest to ensure fixes are effective
• What type of error occurs when the program violates the language's grammar rules and cannot compile or run?

  Syntax Error
• What is an example of a logic error in calculating the area of a rectangle?

  Using addition instead of multiplication
• Testing is essential for creating robust programs.


  True
• Logic errors produce incorrect results due to flaws in the algorithm.


  True
• Syntax errors occur in the structure or grammar
• What is an example of a logic error in code?

  Incorrect calculation
• Testing aims to ensure software functions correctly and reliably.

  True
• Testing is crucial for identifying and fixing errors in software before release.


  True
• What environmental conditions can cause runtime errors during program execution?

  Unexpected inputs
• The purpose of testing in software development is to identify and fix errors or bugs
• Syntax errors refer to violations of the programming language's grammar
• Runtime errors often arise from incorrect input, resource unavailability, or dividing by zero.
