Understanding Function Overloading in C++

Understanding Function Overloading in C++

Comments 412 Comments

Introduction: Function overloading is a powerful feature in C++ that allows multiple functions with the same name to exist in the same scope, provided their parameter lists are different. This feature is a part of polymorphism in Object-Oriented Programming (OOP) and allows developers to implement functions that perform similar tasks but operate on different types or numbers of inputs. What is Function Overloading? Function overloading occurs when: Advantages of Function Overloading: Example Code: Function Overloading in C++ Below is an…

Hypervisors in Cloud Computing

Hypervisors in Cloud Computing

Comments 40 Comments

A hypervisor, also known as a virtual machine monitor (VMM), is a critical software layer in virtualization technology. It allows multiple virtual machines (VMs) to run on a single physical hardware system by managing and allocating resources such as CPU, memory, and storage to each VM. Hypervisors ensure that each VM operates independently, with isolated environments, while sharing the underlying hardware. Imagine you have a single powerful computer, and you want to run multiple operating systems like Windows, Linux, and…

Static Data Members and Functions in C++

Static Data Members and Functions in C++

Comments 28 Comments

In daily life, some things are shared by everyone rather than belonging to just one person. For example, in a classroom the notice board is the same for all students. If one student puts a notice, every student can see it. Similarly, in a society, the water tank is shared by all houses. In C++, such shared values or functions are handled using the static keyword. A static member in C++ belongs to the class itself rather than to individual…

Cloud Computing Architectures Cloud computing architecture refers to the various components and technologies that work together to deliver cloud-based services. These architectures define how computing resources are organized, managed, and delivered over the Internet. The main components of cloud architecture include front-end and back-end platforms, cloud-based delivery models, and networking infrastructure. You can visit the detailed course on cloud computing here. Visit the detailed tutorial here. Front-End Architecture This is the client-side interface that allows users to interact with cloud…

Virtualization in Cloud Computing

Virtualization in Cloud Computing

Comments 3 Comments

Imagine you have a powerful personal computer at home. You are a single person, and you can utilize it up to a maximum of 30%, while the remaining 70% of the resources are wasted. How can you make full use of your computer’s potential? Introduction to Virtualization Virtualization is a technology that allows multiple virtual environments to run on a single physical hardware system. It works by abstracting hardware resources such as CPU, memory, and storage, creating virtual versions of…

Const Data Members and Functions in C++

Comments 125 Comments

In object-oriented programming, we design classes as blueprints for creating objects. A class itself does not store data; it only defines the structure and behavior that objects will have. The actual data is stored in the memory allocated to each object when it is created. While designing software systems, we often encounter values that must not change during program execution. Mathematical constants such as π, configuration limits, fixed rates, and identification codes are examples of such values. If these values…

Introduction to Cloud Computing

Introduction to Cloud Computing

Comments 2 Comments

Cloud computing is a technology paradigm that enables users to access computing resources—such as servers, storage, databases, networking, software, and more, over the internet instead of maintaining physical hardware. These resources are on-demand, scalable, and cost-effective, making cloud computing a vital component of modern IT infrastructure. The full tutorial can be accessed here. Key Characteristics of Cloud Computing On-Demand Self-Service Cloud computing allows users to provision computing resources automatically without requiring human intervention. This feature enables users to scale resources…

Constructors and Destructors in C++

Constructors and Destructors in C++

Comments 26 Comments

C++ gives every object a clear life story: it’s created, used, and then destroyed. To make this safe and predictable, the language runs a special function at birth (to initialize the object) and another at death (to clean up resources). Constructors in C++ Constructors exist to prevent uninitialized state, to let callers pass meaningful values at creation time, and to centralize setup logic in one place. In practice, you’ll use two common kinds; You may define multiple constructors for the…

Understanding Access Modifiers in C++

Understanding Access Modifiers in C++

Comments 125 Comments

What Are Access Modifiers? In C++, access modifiers are keywords used to define the level of access that members of a class (variables and methods) can have. They are essential for ensuring encapsulation, which is a core concept of Object-Oriented Programming (OOP). By using access modifiers, we control how the internal data of a class is accessed, modified, and protected. Access modifiers in C++ include: By controlling access, access modifiers help: Types of Access Modifiers Code Example class number {…
