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

What is a potential downside to overloading operators?

1. It can make the code less intuitive

2. It significantly reduces execution speed

3. It is not supported by all C++ compilers

4. It automatically overrides all default operations

The correct answer is: It can make the code less intuitive

Overloading operators can be detrimental to the code's intuitiveness because it can cause confusion and make it more difficult for other programmers to understand the logic behind the code. This can lead to errors and make the code harder to maintain. Option B is incorrect because overloading operators does not necessarily result in a significant reduction in execution speed. It depends on how the operator is overloaded and the efficiency of the code. Option C is incorrect because overloading operators is supported by most modern C++ compilers. Option D is incorrect because overloading operators allows for customization of specific operations, rather than automatically overriding all default operations.
