Syntax, Logic and Runtime errors 2024

What is a syntax error in programming?

• An error that occurs when the program runs but produces incorrect results.

• An error that occurs when the code does not follow the rules of the programming language.

• An error that occurs due to incorrect logic in the code.

• An error that occurs when the program runs out of memory.

Which of the following is an example of a logic error?

• Misspelling a keyword in the code.

• Forgetting to close a bracket.

• Using the wrong formula to calculate the area of a circle.

• Missing a semicolon at the end of a statement.

What is the main difference between a syntax error and a logic error?

• Syntax errors are harder to find than logic errors.

• Syntax errors prevent the program from running, while logic errors allow the program to run but with incorrect results.

• Logic errors prevent the program from running, while syntax errors allow the program to run but with incorrect results.

• There is no difference between syntax errors and logic errors.

Which of the following is most likely to cause a syntax error?

• Using a variable before declaring it.

• Dividing a number by zero.

• Forgetting to include a library or module.

• Using a single equal sign instead of a double equal sign for comparison.

If a program compiles successfully but produces incorrect results, what type of error is this likely to be?

• Syntax error

• Runtime error

• Logic error

• Compilation error

Which of the following statements is true about logic errors?

• They are detected by the compiler.

• They are easy to fix because they are always obvious.

• They occur when the program's logic is incorrect, leading to unexpected results.

• They occur when the program runs out of memory.

What is a common way to identify logic errors in a program?

• Running the program and checking the output against expected results.

• Using a spell checker on the code.

• Compiling the program to see if there are any errors.

• Checking the syntax of the code.

Which of the following is NOT a cause of syntax errors?

• Misspelling a keyword.

• Incorrect indentation.

• Using an undefined variable.

• Using a wrong operator in a calculation.

How can logic errors be prevented?

• By using a debugger to step through the code.

• By ensuring the code follows the syntax rules of the programming language.

• By using a code formatter.

• By writing test cases to verify the program's output.

Which of the following best describes a runtime error?

• An error that occurs when the program is being compiled.

• An error that occurs when the program is running, often due to invalid operations.

• An error that occurs due to incorrect logic in the code.

• An error that occurs when the code does not follow the syntax rules.
