Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

Placing the opening brace on its own line is recommended because it aids in scannability for complex conditionals, as mentioned in the text. This is because it clearly separates the beginning of the code block, making it easier for readers to identify the start and end of the conditional statement. Option B is incorrect because the C++ standard does not specifically mention this recommendation. Option C is incorrect because elegance is subjective and may differ among readers. Option D is incorrect because while Bjarne Stroustrup is a major contributor to the development of C++, this specific recommendation may not have been explicitly made by him.
