What is Potential Energy? Potential energy is a type of stored energy stored by an object due to its position relative to other objects. It is an important concept in physics and is commonly calculated when studying objects in gravitational fields. In this tutorial, we are going to learn how to calculate the potential energy of an object in C++ if the mass and height are given. Formula for Calculating Potential Energy The formula for potential energy is as follows: Potential Energy = m × g × h Where:m is the mass of the object (in kilograms).g is the gravitational ...

When we start learning to code, practicing star patterns is one of the best ways to improve logic building. One of the simplest yet fascinating patterns is the hollow square pattern. In this article, we are going to learn how to print a Hollow Square Pattern using C++. What is Hollow Square Pattern? A hollow square pattern is a geometrical arrangement of stars forming a square shape, but the stars are present only at the boundary of the square. The stars are printed in such a manner that the edges of the square are filled with stars, while the interior ... Read More

The sum of alternate elements has various real-life applications such as signal processing, data compression, pattern recognition, gaming, and financial data analysis. Problem Description In this article, we are going to learn how to find the sum of alternate elements of an array in C++. Alternate elements are present at even or odd indices of the array, depending on how we define them.  Example 1 Inputarray = [1, 2, 3, 4, 5] OutputSum_even = 9Sum_odd = 6 Explanation The alternate elements at the even index are 1, 3, 5 (at ...

Problem Description In this problem, we are given coordinate points of a 2-dimensional plane and a 3-dimensional plane, and we have to find the distance between these two points. In this article, we are going to discuss how we can find the distance between two points in C++. Approaches to Calculate Distance Between Two Points To solve this problem, here are the two approaches that can you use: Using 2D Coordinates Using 3D Coordinates Using 2D Coordinates In this approach, we use the direct distance formula to calculate ...

Problem Description In this problem, we are given an array that contains all unique elements except one element which is present exactly two times in the array. We have to return that element which is present two times in the array. In this article, we are going to learn how we can find duplicates in an array of N+1 integers in C++. Example Input: array = {1, 3, 4, 2, 2} Output: 2 Explanation: 2 is the only element in the array that occurs two times. Approaches to Find Duplicate Element in an Array ... Read More

Problem Description We are given the three sides of a triangle, and we have to calculate the area of the triangle using Heron's formula. In this article, we are going to discuss how we can calculate the area of a triangle using Heron's Formula in C++. Heron's Formula The formula for calculating the semi-perimeter of the triangle is: s = (a + b + c) / 2 Then, apply Heron's formula to calculate the area of the triangle. Heron's formula for calculating the area of the triangle is: Area = √ s * (s - a) * (s - ... Read More

Problem Description In this problem, we are given a number and have to check whether this number is greater than zero. Using the if-else and ternary approach to check if the given number is greater than zero, equal to zero, or less than zero. In this article, we will discuss how we can find if a given number is greater than zero or not in C++. Prerequisite If-else operator: This operator allows the program to execute certain code blocks based on whether a condition is true or false. Syntax of If-else operator if (condition) { // ...

Problem Description In this problem, we are given two numbers and we have to find the value obtained after subtracting one number from another. In this article, we are going to learn how we can subtract two numbers in C++ using different approaches. Example 1 Input number1 = 8number2 = 12 Output 4 Explanation The subtraction of number2 - number1 i.e. 12 - 8 will result in 4. Example 2 ... Read More

What is a Vector in C++?A vector is a dynamic array as the size of the vector changes during the program's execution. If we insert more elements in the vector it expands its size and if we remove elements from the vector it shrinks in size. A vector is part of the Standard Template Library (STL). Problem DescriptionIn this problem, we are given a vector and have to insert an element at a certain position. In this article, we are going to learn how to insert multiple positions in a vector in C++ using different approaches. Below are some examples to ... Read More
