What is Debugging?

The video tutorial by Aishwarya Saxena from Purple Tutor covers the topic of debugging in programming. It begins with an introduction to debugging, explaining it as the process of finding and fixing errors in code. The tutorial then discusses two main types of errors: syntax errors, which are violations of language rules, and logic errors, which occur when the code is correct but produces incorrect results. The video outlines steps for debugging, including checking for basic errors, examining error lines, and using a top-down approach. A debugging checklist is provided, emphasizing the importance of checking syntax and using reference materials. Finally, the tutorial offers advice on error prevention and testing, such as embracing strong programming practices and testing code with variable boundary values.

What is the primary goal of debugging in programming?

• To design user interfaces

• To write new code

• To find and fix errors in code

• To compile code

Which type of error occurs when the code violates language rules?

• Logic error

• Syntax error

• Semantic error

• Runtime error

What is a logic error in programming?

• An error that occurs due to hardware failure

• An error that prevents the code from compiling

• An error that results in incorrect output despite correct syntax

• An error that causes the program to crash

What should you do first when debugging a program?

• Rewrite the entire code

• Run the program

• Fix all basic errors

• Check the internet for solutions

Why might a single syntax error appear as multiple errors in a program?

• Because the compiler is outdated

• Because of interdependencies between lines of code

• Because the code is too long

• Because of incorrect variable names

What is a recommended approach when you are confident a line of code is correct but an error is shown?

• Ask a friend for help

• Check the previous lines for syntax mistakes

• Rewrite the entire program

• Ignore the error

What should you do if you cannot resolve a particular error quickly?

• Move on to other errors and return later

• Restart the computer

• Delete the problematic code

• Focus on it until it's fixed

What is a key component of a debugging checklist?

• Ignoring syntax errors

• Checking case rules and spellings

• Using only online resources

• Skipping error messages

Why is it important to test code using variable boundary values?

• To ensure the program runs faster

• To check if the program handles edge cases correctly

• To make the code look cleaner

• To reduce the number of lines in the code

What is a good practice to prevent errors in programming?

• Skipping testing phases

• Copying code from unauthorized sources

• Using strong programming and design practices

• Avoiding code reviews
