Encapsulation is one of the fundamentals of OOP object-oriented programming. It refers to the bundling of data with the methods that operate on that data. Publicly accessible methods are generally provided in the class so-called getters and setters to access the values, and other client classes call these methods to retrieve and modify the values within the object.
If we want to use the data stored in an object to perform an action or calculate a derived value, we define a method associated with the object which does this. In the below example: There are three files. This file acts as a link between the data scattered over multiple files.
When this is executed then function call is made to functions in which are defined in other C files along with structures. Malloc function allocates the memory. Encapsulation is the leading step towards object-oriented programming.
This article gives information about Encapsulation in C. The benefit of properties is that the users can manipulate the object from an internal data point of view using a single named item having data and functionality defined in it. This is a guide to the Encapsulation in C. Here we discuss the introduction and need of encapsulation in C along with Advantage and examples.

In this case, the interface is abstracted away from the actual implementation of the code. Containers are a relatively new type of software that can be used to virtually package a piece of code along with all of its libraries and other dependencies that it needs to execute. Containers create an encapsulated virtual environment where an application can be launched using the minimum amount of storage space and computing power. A group of containers can share access to a single operating system and draw their computing resources from a single piece of hardware.
Containerization has emerged as an alternative to virtual machines because of its highly efficient usage of computing resources. Virtualization allowed multiple operating systems and applications to run at the same time while sharing the resources of a single computer. Containers improved on this model by sharing a host operating system and installing the container runtime engine onto the host machine's operating system. A computer running four virtual machines expends additional resources for each instance of the operating system that it runs, while a computer with an installed containerization engine could run the same number of applications on a single operating system.
As a result, multiple containers can operate using the same computing capacity as a single virtual machine. Containers are just one example of encapsulation in coding where data and methods are bundled together into a single package. As we mentioned earlier, encapsulation in object oriented programming allows developers to bundle data and methods together but it can also be used to hide sensitive data that should not be exposed to users.
A getter method is used to retrieve the value of a specific variable within a class. A setter method is used to set or update the value of a specific variable within a class. Most of us have learnt to make class members private by default unless we really need to expose them. That's just good encapsulation. This is applied most frequently to data members, but it applies equally to all members, including virtual functions.
