Answer to Question #298085 in C++ for Kelly

Question

Using Struct

1. Program Sample Run 1

For first point:

Enter the value of x coordinate: 0

Enter the value of y coordinate: 3

For second point:

Enter the value of x coordinate: 4

Enter the value of y coordinate: 0

The distance between two given points is 5.

2. Program Sample Run 2

For first point:

Enter the value of x coordinate: -2.1

Enter the value of y coordinate: 3

For second point:

Enter the value of x coordinate: -9.12

Enter the value of y coordinate: 5

Answer 1

#include <iostream>


struct Point
{
    double x, y;
};


double distance(Point p1, Point p2)
{
    return sqrt((p2.x - p1.x) * (p2.x - p1.x) + (p2.y - p1.y) * (p2.y - p1.y));
}


int main()
{
    Point p1, p2;
    std::cout << "For first point:\nEnter the value of x coordinate : ";
    std::cin >> p1.x;
    std::cout << "Enter the value of y coordinate : ";
    std::cin >> p1.y;


    std::cout << "For second point:\nEnter the value of x coordinate : ";
    std::cin >> p2.x;
    std::cout << "Enter the value of y coordinate : ";
    std::cin >> p2.y;


    std::cout << "The distance between two given points is " << distance(p1, p2) << ".\n";
  


    system("pause");
    return 0;
