This tutorial will discuss how to modify elements while iterating over a set in C++. A set contains only unique elements. Moreover, the values in the set act as keys. Once an element is inserted into the set, its value cannot be changed. Modifying its value could disrupt the internal ordering of elements in the […]

This tutorial will discuss the differences between begin() and cbegin() of set in C++. Table Of Contents begin() function of Set cbegin() function of Set In C++, both begin() and cbegin() are member functions of class set. They both returns an iterator pointing to the first element of the container. However, there’s a subtle difference

This tutorial will discuss multiple ways to use lambda function during set iteration in C++. Table Of Contents Using std::for_each() and Lambda Function Using Range Based For Loop and Lambda Function Using std::for_each() and Lambda Function Suppose we have a set of integers. If we want to iterate over all the elements in this set

This tutorial will discuss how to use range based for loops with set in C++11 and later. In C++11, the range-based for loop was introduced. It allows us to iterate over a sequence of elements without explicitly using an iterator or random-access operators. In the range-based for loop, we only need to specify a variable

This tutorial will discuss the different kind of iterators a Set provides in C++. Table Of Contents Bidirectional Iterator Const Iterator : const_iterator Reverse iterator Const Reverse iterator In C++, the Set class provides bidirectional iterators. This means we can increment and decrement the iterators, but we cannot perform arithmetic operations on them like we

This tutorial will discuss about the set clear() function in C++ stl. Table Of Contents Syntax of set::clear() function Example of std::clear() function Scenarios for Exceptions and Undefined Behavior with set::clear() In the C++ Standard Template Library (STL), the set is a container that ensures a sorted sequence of unique elements. The clear() member function

This tutorial will discuss about the set cend() function in C++. Table Of Contents Syntax od set::cend() Example of set::cend() Scenarios for Exceptions and Undefined Behavior In C++, the set container from the Standard Template Library (STL) provides a way to store unique elements in a sorted sequence. To traverse or iterate over these elements,

This tutorial will discuss about the set size() function in C++ stl. Table Of Contents Syntax of set::size() function Example of set::size() Scenarios for Exceptions and Undefined Behavior with set::size() The C++ set container, which is a part of the Standard Template Library (STL), is designed to store unique elements in a sorted sequence. The
