What is the difference between syntax errors and logic errors in code?

• Syntax errors are intentional, while logic errors are accidental

• Syntax errors are easy to fix, while logic errors are difficult to identify

• Syntax errors occur during runtime, while logic errors occur during compilation

• Syntax errors are related to the structure of the code, while logic errors are related to the behavior of the code.

Answer explanation

Syntax errors are related to the code structure, while logic errors are related to code behavior.

When troubleshooting code logic, what is the best approach to identify the issue?

• Guess randomly and make changes to the code

• Use a systematic approach such as debugging, reviewing the code, and testing different scenarios.

• Ask someone else to fix the problem

• Ignore the issue and hope it goes away on its own

Answer explanation

The best approach to identify code issues is to use a systematic approach such as debugging, reviewing the code, and testing different scenarios.

Which of the following is an example of a common coding error in programming?
