Double pointers play a crucial role in the implementation of various data structures. For example, in linked lists, a double pointer can be used to modify the head of the list within a function. Similarly, in trees and graphs, double pointers are often used to manage dynamic node allocations...
we will learn what is a double pointer, how to declare them and how to use them in C programming. To understand this concept, you should know thebasics

C++ provides two primary smart pointer types: std::unique_ptr and std::shared_ptr. We’ll focus on std::unique_ptr for our solution. Let’s dive into a complete working code example demonstrating the usage of std::unique_ptr to prevent double free errors: #include <iostream> #include <...
