In C++, vectors are dynamic arrays that can grow and reduce in size as per requirements. Sometimes, we may need to copy the contents of a vector to the POD array. In this article, we will learn how to copy a vector to an array in C++....

In C++, a thread is a basic element of multithreading that represents the smallest sequence of instructions that can be executed independently by the CPU. In this article, we will discuss how to access a vector from multiple threads safely in C++....

In C++, a map is a container that stores elements in the form of a key value and a mapped value pair. In this article, we will learn how to access a value in a map using an iterator in C++....

In C++, sets are the data containers that store the unique elements in some specified order. Concatenating two sets means merging the elements of two sets into the first set. In this article, we will learn how to concatenate two sets in C++ STL....

The match_results::empty() is a inbuilt function in C++ which returns True if the smatch object contains no matches.Syntax:...

In C++, a list is a sequence container provided by the STL library that represents a doubly linked list and allows us to store data in non-contiguous memory locations efficiently. In this article, we will learn how to copy one list to another in C++....

In C++, the vector is a dynamic array that can resize itself automatically to accommodate new elements. In this article, we will learn how to declare a vector in C++....

In C++, a set is an associative container that stores unique elements in a sorted order. In this article, we’ll explore different approaches to check if a set is empty in C++ STL....

The unordered_multiset::max_bucket_count() is a built-in function in C++ STL which returns the maximum number of buckets that the unordered multiset container can have. This is the maximum it can have, it cannot exceed despite the collisions due to certain limitations on it....

Given string str, we need to print the reverse of individual words....

...

Given an array arr[] and a number k. The task is to delete k elements which are smaller than next element (i.e., we delete arr[i] if arr[i] < arr[i+1]) or become smaller than next because next element is deleted....
