Description: A non-member function in C++ is a function that is not associated with any specific class. Unlike member functions, which operate on the data of a class instance and have access to its attributes and methods, non-member functions are independent and can be used anywhere in the code. These functions are fundamental to structured programming and allow for code modularity, facilitating reuse and organization of tasks. Non-member functions can be declared and defined outside of any class, making them more versatile in their use. Additionally, they can take parameters and return values, making them useful for performing calculations, manipulating data, or executing specific tasks without the need to create an object of a class. In C++, non-member functions can also be overloaded, meaning multiple functions can be defined with the same name but with different types or numbers of parameters. This provides great flexibility and allows programmers to create more intuitive and user-friendly interfaces. In summary, non-member functions are an essential part of programming in C++, providing a way to structure code efficiently and effectively.
