What is the c plus plus program to calculate the distance between two coordinates?

Answer 1

#include<iostream>

struct point

{

int x;

int y;

point (const int _x, const int _y): x {_x}, y {_y} {}

double distance (const point&) const;

};

double point::distance (const point& p) const

{

int w = x - p.x;

int h = y - p.y;

return sqrt (h*h + w*w);

}

std::ostream& operator<< (std::ostream& os, const point& p)

{

return os << '{' << p.x << ", " << p.y << '}';

}

int main()

{

using namespace std;

point a {5,10};

point b {7,2};

double d = a.distance (b);

std::cout << "The distance between coordinates " << a << " and " << b << " is " << d << ".\n" << std::endl;

}
