Hello everyone! Today we are going to talk about one of the most powerful yet confusing features of the C language for beginners – pointers. Through several practical examples, let’s master this core concept step by step. A pointer is essentially a variable that stores a memory address. Imagine it like the house number, telling … Read more
In the world of data structures, a HashMap is an efficient tool for storing and retrieving data. It stores data in the form of key-value pairs, allowing for insertions, deletions, and lookups to be performed in average constant time complexity. Today, we will implement a simple HashMap using the C programming language. 1. Introduction to … Read more
