The memcpy function in C copies n characters from the object pointed to by src into the object pointed to by dst. In this blog post I will not explain about the memcpy but I will explain the common issues which occurs if not use the memcpy function properly in C programming. So, let’s see

In this blog post, I will explain the range-based for loop with the help of example code. The range-based for loop is introduced in C++11. It executes a for loop over a range and is more readable equivalent to the traditional for loop. See the below syntax for the range-based for loop. Syntax: for (

Destructors are used to release any resources allocated by the object. In this blog post, I will explain when to use virtual destructors in C++. But before explaining it I want to tell you some contexts where the destructor is invoked implicitly. Let’s see a few of them, For a constructed object with static storage

In this blog post, you will learn how to call a base class function from a derived class function in C++. The primary prerequisite to solving this problem is an understanding of inheritance. So here I assumed you have already an understanding of inheritance in C++. So let’s get started with the problem statement. Problem

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,

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 how to initialize a vector in C++ with the help of C++ programs. I have already written an article on vectors if you want you can check it; “C++ vectors“. Now comes the topic of how we can initialize the C++ vector. I will go through the different

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
