Final Answer:
The given statement "By default, are all the member functions of a class global?" is False because by default, member functions of a class are not global; they are associated with the class and operate within its scope. Thus, the correct answer is option b. False.
Step-by-step explanation:
In object-oriented programming, the member functions of a class are not inherently global. By default, they are associated with the class and its instances. Each instance of a class has its own set of member functions, which are separate from those of other instances. This encapsulation is a fundamental concept in OOP, allowing for better organization and control of code.
Member functions operate within the scope of the class, and their access can be controlled through access specifiers like public, private, or protected. Public member functions are accessible from outside the class, while private ones are restricted to the class itself. This encapsulation ensures that the internal workings of a class are hidden from external code, promoting modularity and reducing potential conflicts.
In contrast, global functions are not associated with any class and can be accessed from anywhere in the codebase. The distinction between member functions and global functions is crucial for building modular and maintainable software.
Thus, the correct answer is option b. False.
