1. Introduction

Memory management is at the heart of computer programming. Whether you’re building a desktop app, embedded system, or operating system kernel, understanding how memory works is crucial. While modern programming languages like Java, Python, or C# abstract much of this complexity, older and lower-level languages like C/C++, Pascal, and BASIC expose or simulate different memory models.

In this article, we will explore how stack and heap memory are implemented in C/C++, how they compare to Pascal and BASIC, and what each language teaches us about managing memory efficiently.
