The general syntax for accessing a namespace member is typically "namespace_name::identifier", using the scope resolution operator "::" instead of the arrow operator "->". This syntax can be used to access variables, functions, or other members that have been defined within a namespace.

For example, if a variable called "x" is defined within the namespace "MyNamespace", you could access it using the following syntax:

MyNamespace::x

Or if you have a function called 'myfunction' within the same namespace you could call it using

MyNamespace::myfunction();

Please note that this is the general syntax, some programming languages might have a slightly different way of accessing namespace members or even don't have namespaces.

Explanation: Are usually for telephone, TV and other communication lines.

A triangle is an object which has the main program as a shape triangle. The first line of code in the main program is Shape Triangle.

The goal of the object-oriented approach is to break down the behavior and structure of information systems into manageable modules that incorporate both data and process. By making system analysis and design more accessible, object-oriented design (OOD) aims to increase both the quality and productivity of these processes.

Encapsulation, inheritance, and polymorphism are the three main pillars that support object-oriented programming.

A class is a template declaration of the variables and methods in a certain type of object in object-oriented programming. As a result, an object is a particular instance of a class; instead of variables, it holds real values. One of the fundamental concepts of object-oriented programming is class.
