In C++, a unique_ptr is a smart pointer that owns and manages dynamically allocated memory. It automatically deletes the linked memory when the unique_ptr goes out of scope. One key aspect of unique_ptr is ownership uniqueness, meaning that there can only be one unique_ptr pointing to any given resource at a time. This uniqueness is […]

In this article, we will discuss about the make_unique<>() in C++ and what are its advantages. In the modern C++, memory management has been made significantly easier and safer through smart pointers. The std::make_unique<T>() is a utility function introduced in C++14. It lets the C++ runtime system handle memory allocation without the programmer needing to

Smart Pointers were introduced by C++11 Standard. Smart pointers are a significant advancement that addresses the longstanding challenge of memory management in C++ programming. The Problem of Memory Management Traditionally, managing memory in C++ has involved two primary operations: allocating memory with the new operator and releasing it using the delete operator. This manual process

This tutorial will discuss how to remove all occurrences of an element in a Python list. To remove all occurrences of an element from a list, we can iterate over all the elements of the list and skip the elements we don’t want to include. This can be accomplished using list comprehension. We’ve created a
