3. Producing robust programs

What is the main purpose of testing in programming?

• To add new features to the program

• To help the programmer remove bugs and ensure the program functions as intended

• To make the program run faster

• To change the programming language used

What is iterative testing?

• Testing the program only once after completion

• Testing a section of code repeatedly during development

• Testing the program without any code

• Testing only the user interface

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

• Using a variable before it has been declared

• The program not producing the expected output

• The program running slower than expected

• The program crashing due to insufficient memory

What is a logic error in programming?

• An error in the way a program works, not doing what it is expected to do

• An error that prevents the program from compiling

• An error that causes the program to run faster

• An error that changes the programming language

What is a common cause of logic errors in programming?

• Incorrectly using logical operators

• Correctly using syntax

• Using valid data

• Writing comments in code

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

• Syntax errors stop the program from running; logic errors do not.

• Logic errors stop the program from running; syntax errors do not.

• Both errors stop the program from running.

• Neither error affects the program's execution.

What type of test data is described as data that the program should accept and be able to process?

• Valid data

• Extreme data

• Invalid data

• Erroneous data

What is the purpose of a test plan in programming?

• To list all tests to ensure the program functions as intended

• To write the program's code

• To design the user interface

• To compile the program

What is the purpose of the program described in the text?

• To calculate the sum of numbers

• To check if a number is within a specific range

• To sort a list of numbers

• To multiply two numbers

Which of the following is considered a valid test data for the program?

• 0

• 5

• 11

• -3
