In this problem, we are given a string num which is a large number. Our task is to create a program to find remainder when large number is divided by 11 in C++.Problem Description − We need to find the remainder when the number defined by the string is divided by 11.Let’s take an example to understand the problemInputnum = “43212981843718452”Output7Solution ApproachTo find the remainder, we obviously need to divide the number. But dividing huge number is a complex process so to ease up the process, we will divide digit by digit. And store the remainder that follows. This process ... Read More

In this tutorial, we will be discussing a program to find prime numbers between given intervals.For this we would be provided with two integers. Our task is to find the prime numbers in that particular range.Example Live Demo#include using namespace std; int main() {    int a, b, i, j, flag;    //getting lower range    a = 3;    //getting upper range    b = 12;    cout

In this problem, we are given the side of a square (A) and the length and breadth of a rectangle (L and B). Our task is to create a Program to find Perimeter / Circumference of Square and Rectangle in C++.Problem Description:To find the circumference of a square, we need the side of the square (a). For that, we will use the formula for the perimeter of the square which is 4a.To find the circumference of a rectangle, we need the Length (L) and breadth (B) of the rectangle. For that, we will use the formula for the perimeter of ... Read More

In this tutorial, we will be discussing a program to find parity.For this we will be provided with a number. Our task is to find its parity i.e count of whether the number of ones are odd or even.Example Live Demo# include # define bool int using namespace std; //finding the parity of given number bool getParity(unsigned int n) {    bool parity = 0;    while (n){       parity = !parity;       n = n & (n - 1);    }    return parity; } int main() {    unsigned int n = 7;    cout

In this problem, we are given input from the user. Our task is to create a program to find out the data type of user input in C++.Problem Description − We will take input from the user and check the data type of the input value.Let’s take an example to understand the problem, Example 1:Input − 34Output − It is an integerExample 2:Input − tutorialspointOutput − It is a stringSolution Approach:We will check if the input string is a number or not a number.If it is a number, we will check if it is an integer or a float value.If ...
