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

Why might a C++ programmer prefer to specify the members of a class as 'public' right at the beginning?

1. To enhance readability by showing the interface first

2. Because private members must be declared at the end

3. To avoid compilation errors

4. C++ standards require it

The correct answer is: To enhance readability by showing the interface first

This is because it is considered good practice to show the interface of a class first, in order to easily understand the functionality and capabilities of the class. It also helps with readability and organization. Options B and C are incorrect because private members can be declared at any point in the class and doing so does not necessarily prevent compilation errors. Option D is incorrect because while C++ standards do not explicitly require it, it is a common convention and recommended practice to declare public members at the beginning of a class.
