[Solved] Distance between 2 points with Java, C++, Python

Write a program to find the distance between 2 points using functions.

Input Format:

Input consists of 4 integers. The first and second integer corresponds to the x-coordinate and y-coordinate of the first point. The third and fourth integer corresponds to the x-coordinate and y-coordinate of the second point.

Output Format:

Output consists of a single floating point number (correct to 2 decimal places.) Refer sample output for formatting details.

Sample Input:

3

6

4

3

Sample Output:

Distance between the 2 points is 3.16

Solution

import java.util.*;
import java.text.DecimalFormat;
import static java.lang.Math.*;
import static java.lang.Math.sqrt;
public class Main {
    public static void main(String[] args) {
        DecimalFormat format = new DecimalFormat("0.00");
        int a, b, c, d;
        Scanner s = new Scanner(System.in);
        a = s.nextInt();
        b = s.nextInt();
        c = s.nextInt();
        d = s.nextInt();
        float dis = findDistance(a, b, c, d);
        //sauravhathi
        System.out.println("Distance between the 2 points is " + format.format(dis));
    }
    public static float findDistance(int p, int q, int r, int s) {
        float temp;
        temp = (float) sqrt(pow(r - p, 2) + pow(s - q, 2));
        return temp;
    }
}

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
    int a,b,c,d;
    cin >> a >> b >> c >> d;
    //sauravhathi
    printf("Distance between the 2 points is %.2f\n", sqrt(pow(c-a,2)+pow(d-b,2)));
    return 0;
}

a = int(input())
b = int(input())
c = int(input())
print("Distance between the 2 points is %.2f\n", sqrt(pow(c-a,2)+pow(d-b,2)));
