You will learn to solve the problem of how to write a C++ program to remove duplicates from a sorted array. So the important point is that the array is already sorted in either ascending or descending order. Now let’s see the problem statement, Problem Statement: Given an integer array “arr“, sorted in increasing order, […]

Given an array arr[] of n numbers and another number target, the task is to check whether or not there exist two elements in arr[] whose sum is exactly the target. That means you just need to find whether or not there exist two elements in an array whose sum is exactly equal to the

In this blog post, you will learn C++ vectors with the help of programming examples. This article will be long because I will try to cover most of the important points related to vectors. So hopefully you will love this ultimate Guide to C++ Vector. So let’s start this article with this question what vectors

In this blog post, you will learn what std::reverse() is with the help of a C++ programming example. So let’s first understand std::reverse(). std::reverse() is a built-in function in C++’s Standard Template Library. It is defined in <algorithm> the header file. It reverses the order of the elements in the given range [first, last). Now

In this blog post, you will learn how to change the integer type used by an enum C++. One point you should remember is that what I will explain here only applies to C++11 or above. You cannot do this in C++98/03. So without wasting time let us see a syntax to how we can

In this blog post, you will learn about templates in C++ with the help of programming examples. Templates are powerful features of C++ that allow us to write generic programs. It allows us to define a family of classes, functions, or variables, an alias for a family of types, or a concept. That means as a
