Iterate over a Set in Reverse Order in C++

This tutorial will discuss multiple ways to iterate over a set in reverse order in C++. Table Of Contents Using reverse_iterator Using C++20 Ranges Library Using reverse_iterator In STL, the set class provides a reverse iterator, named reverse_iterator. Using this iterator, we can iterate over the set elements in reverse order. The set function rbegin() […]

Find the distance between two Iterators in a Set in C++

This tutorial will discuss how to find the distance between two iterators in a set in C++. In C++, if you have a set containing various numbers and you want to determine the distance between two specific iterators, you can use the std::distance() function from the Standard Template Library (STL). For instance, suppose you have

How to Use Lambda function during Set Iteration in C++?

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

How to Use Range Based For Loops with Set in C++11 and later?

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

Difference between begin() and cbegin() of Set in C++

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

What Kind of iterators does a Set provide in C++?

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
