In C++, we can return a pointer from a function which is useful when we want to return large data structures that cannot be returned by value. However, it must be done carefully to avoid memory leaks, dangling pointers, and other issues related to dynamic memory management. In this article, we will learn how to return a pointer from a function in C++....

In C++, we may often find the need to extract the file extension from a given path of the file while working in many applications for processing or validating. In this article, we will learn how to get the file extension in C++....

In C++, arrays are static data structures with a fixed size, hence directly adding new elements at the front or middle is not supported in C++ like any other dynamic data structure. In this article, we will learn how we can add an element at the beginning of an array in C++....

In C++, when we have a class template that inherits from a template base class, we need to explicitly use this pointer to access members of the base class. In this article, we will learn why it is necessary to access template base class members through ‘this’ pointer in C++....

In C++, the list is a sequence container that stores data in non-contiguous memory allocation. It is defined in the STL (Standard Template Library) inside the <list> header. In this article, we will learn how to find the first occurrence of a specific element in a list in C++....

In C++, lists are sequence containers that allow non-contiguous memory allocation. They are implemented as doubly-linked lists. The frequency of a specific element means how many times that particular element occurs in a list. In this article, we will learn how to find the frequency of a specific element in a list in C++ STL....

In C++, deques also known as double-ended queues are sequence containers with the feature of insertion and deletion on both ends. In this article, we will learn how to find the first occurrence of a specific element in a deque in C++....

In C++, deques also known as double-ended queues are sequence containers that allow the users to insert and delete elements from both ends efficiently. In this article, we will learn how to find the last occurrence of a specific element in a deque in C++....

In C++, a deque (double-ended queue) is a data structure that allows efficient insertion and deletion at both ends. In this article, we will learn to remove an element from the beginning of a deque in C++....

In C++, deques are sequence containers similar to queues but unlike queues, deques allow the insertion and deletion of elements from both ends efficiently. Vectors are dynamic arrays that can resize themselves during the runtime. In this article, we will learn how to create a deque of vectors in C++....

In C++, a deque is a flexible data structure that supports the insertion and deletion of elements from both ends efficiently. In this article, we will learn how to add an element at the end of a deque in C++....

In C++, deques are containers that allow efficient insertion and deletion operations from both ends. Multisets are associative containers similar to sets but unlike sets, multisets allow duplicate insertions as well. In this article, we will learn how to create a deque of multiset in C++....
