In mathematics, the distance of a point with coordinates (x, y) from the origin is the square root of the sum of x-squared and y-squared. Assume that Point has already been defined as a structured type with two double fields, x and y, define a function getR that takes as an argument a value of type Point and returns the distance of that point from the origin (as described above).

#include <iostream>#include<cmath>using namespace std;struct Point{ double x; double y;};double getR(Point p){ double d = sqrt(pow(p.x,2) + pow(p.y,2)); return d;}int main(){ Point p1; p1.x = 3; p1.y = 4; cout<<getR(p1); return 0;}

Explanation:

The solution is written in c++.

Firstly, create a struct type Point with two double fields, x and y (Line 5 - 8).

Create a function getR that accept a Point type object (Line 10). This function will calculate the distance from origin by applying the formula and then return distance (Line 11 - 12).

In main program, we create a Point object, p1, (Line 17 -19) and test the function by passing the p1 object as argument (Line 21). We shall get the sample output 5.

a social news website is an internet website that features user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the slashdot and fark websites, administrators decide which articles are selected for the front page. on reddit and digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a social networking function, in that users can set up a user profile and follow other users' online activity on the website.
