In this blog post, you will learn how to write a C++ Program to check if a given number is Palindrome or not. But before writing the C++ code if a given number is Palindrome or not first let’s understand what a palindrome number is. A number is called a palindrome number if the reverse […]

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
An enumeration is a distinct type (user-defined type) with named constants that are known as enumerators. The name of the enumeration becomes an enum name within its scope. In C++, the enumeration type is declared with an enum key. These enum keys can be only an enum or enum class or enum struct. The enum
