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

In C++, the copy constructor enables us to initialize an object using another object of the same class. In this article, we will learn, how to implement a copy constructor for deep copying....

A dynamic array is an array that can grow, resize itself, contains a dynamic table, which is mutable in nature, or an array list is randomly accessible, the variable-size list data structure that allows elements to be added or removed....

The std::is_trivially_copy_assignable template of C++ STL is present in the <type_traits> header file. The std::is_trivially_copy_assignable template of C++ STL is used to check whether T is trivially copy assignable type or not. It return the boolean value true if T is trivially copy assignable type, otherwise return false....

The match_results::operator[] is a built function in C++ which used to get the i-th match in the match_result object. It gives the reference to the match at the position given inside the operator.Syntax:...

The match_results::operator= is used to replace all the matches in a smatch object with new matches from another smatch object.Syntax:...

std::mt19937(since C++11) class is a very efficient pseudo-random number generator and is defined in a random header file. It produces 32-bit pseudo-random numbers using the well-known and popular algorithm named Mersenne twister algorithm. std::mt19937 class is basically a type of std::mersenne_twister_engine class....

In C++, the classes are blueprints for creating objects with specific properties and methods that provide a feature of access specifiers to the user through which they can control the access of the data members present in a class. In this article, we will learn how to create a class with private and public members in C++....

A class is a building block in C++ that leads to Object-Oriented programming. It is a user-defined type that holds its own data members and member functions. These can be accessed by creating an instance of the type class....

The match_results::length() is a inbuilt function in C++ which is used to return the length of a particular match in the match_results object.Syntax:...

In C++, classes provide a way to define custom data types that can encapsulate data and methods related to that data. Getter and setter methods are commonly used to access and modify private member variables of the class allowing for the controlled access and modification of data. In this article, we will learn how to create a class with getter and setter methods in C++....
