In C++, the sizeof operator is used to find how much memory a data type uses in bytes. This is useful for understanding memory usage and writing efficient code. Below is a simple C++ program that prints the sizes of int, float, double, and char. Example Code #include <iostream> using namespace std; int main() …

For Enterprise software, reliable and efficient code with a robust memory architecture is critical. In this article, we will learn about how smart pointers have improved memory management in C++. The Problem with Raw Pointers in Enterprise Applications C++ is still one of the fastest languages to make an application. However, proper memory management remains …

This article explores how to design a robust Observer pattern in C++ using modern features, with small code snippets to illustrate the concepts. Why the Observer Pattern? In an event-driven system, one component will react to other independent events. For example, a button click might trigger a change in view, display, etc. Without a proper …

In C++, the scope of a variable refers to the region of the code where that variable is accessible and valid. Understanding variable scope is essential for writing clean, efficient, and bug-free code. Let’s break it down clearly and deeply with examples. Types of Variable Scope in C++ C++ primarily defines four types of variable …
In any distributed system, logging is an important part as it allows for finding bugs, tracking how services are working and figuring out why things may fail. But the logger itself must be fast, thread-safe, and not block other parts/ add delay to your program. This article will go over different techniques you can use …

In this tutorial, we will learn to create a Thread Safe Singleton Pattern for a scalable system. This is a very simple but important concept for any developer working on or creating an application using C++. What is the Singleton Pattern? Why Singleton is Useful in Scalable Systems? A Singleton pattern ensures that a …

Function overloading is a powerful feature in C++ that allows us to define multiple functions with the same name, as long as their parameters differ in type, number, or order. This makes our code more readable and flexible, especially when we want the same function name to behave differently based on the input type. In …
Override Identifier in C++ – Explained with Examples Imagine you have a parent and a child. The parent has a rule, like “Always be polite.” The child wants to follow the same rule but in their own way. In C++, when a child class follows (or overrides) a rule from the parent class, we use …
If you’re new to programming, learning C++ can seem intimidating. But don’t worry you’re not alone! You might notice that C++ has two types of data structures (structs) and classes (classes).At first glance, they might seem similar. After all, both can contain variables and functions. It’s important to understand how they behave under the hood …
The Bellman-Ford algorithm is a classical approach for finding the shortest path from a single source node to all other vertices in a weighted graph, even when the graph contains negative weight edges. Unlike Dijkstra’s algorithm, Bellman-Ford is capable of detecting negative weight cycles.In this post, we implement Bellman-Ford using a simple nested loop structure, …
