Q. Calculate distance between two points ?

THE OUTPUT WOULD BE

#include<stdio.h>
#include<conio.h>
#include<math.h>
  void main( )
  { clrscr( );
float x1,x2,y1,y2,d;
printf("Enter x1:");
scanf("%f",&x1);
printf("Enter x2:");
scanf("%f",&x2);
printf("Enter y1:");
scanf("%f",&y1);
printf("Enter y2:");
scanf("%f",&y2);
d=sqrt(pow(x2-x1,2)+pow(y2-y1,2));
printf("Distance b/w two points :\n");
printf("%.2f",d);
getch( );
  }
