Can we use the same function name for a member function of a class and an external function in the same program file if yes, how are they distinguished if no, please give reasons?
Yes. The class object is used to distinguish between the member function of a class and a non-member function with the same name.

How do you use functions in class?
The definition of member functions can be inside or outside the class definition. If the member function is defined inside the class definition, it can be defined directly, but if it is defined outside the class, then we have to use the :: scope resolution operator along with the class name along with the function name.
Where can you use classes in Python?
The class creates a user-defined data structure, containing its own data members and member functions, which can be accessed and used by creating an instance of that class. A class is like a model for an object. Some points about the Python class: Classes are created by keyword class.
Where do you declare the function of members in a class?
The member function is declared inside the class as a normal function. This declaration informs the compiler that the function is a member of the class and has been defined outside the class. After a member function is declared inside the class, it must be defined (outside the class) in the program.
Do you need classes in Python?
Classes are great if you need to maintain state, because they contain data (variables) and behaviors (methods) that act on that data and need to be grouped together logically. This leads to code that is better organized (cleaner) and easier to reuse.
How to access member functions of a class?
Access to data members and member functions: The data members and member functions of the class can be accessed using the dot operator (‘.’) with the object. For example, if the name of the object is obj and you want to access the member function named printName(), you would type obj.printName().
How are member functions defined in C++?
In this article, you will learn about C++ classes and functions. You will learn about different ways to define class member functions. Functions associated with a class are called member functions of that class. Member functions must be declared inside the class, but can be defined inside or outside the class.
Can a function be declared inside a class?
Member functions must be declared inside the class, but can be defined inside or outside the class. There are two ways to define member functions:
How are classes and objects used in C++?
Last updated: May 17, 2021 Class: A class in C++ is the building block that leads to object-oriented programming. It is a user-defined data type, containing its own data members and member functions, which can be accessed and used by creating an instance of that class. A C++ class is like a model for an object.
