Program to calculate distance between two points

Program to calculate distance between two points

#include<stdio.h>
#include<math.h>
int main()
{
    float x1,x2,y1,y2,D;
    printf("Enter the point x1,x2\n");
    scanf("%f%f",&x1,&x2);
    printf("Enter the value of y1,y2\n");
    scanf("%f%f",&y1,&y2);
   D=sqrt(pow((x2-x1),2)+pow((y2-y1),2));
  printf("Distance betweent two points=%f",D);
}

OUTPUT
Enter the point x1,x2
4
2
Enter the value of y1,y2
5
1
Distance between two points=4.472136

this program is best example  of combination of sqrt and pow function
In this program we use these function for calculating distance between two points.
