IO 4

Description:

Given two cities at geographic coordinates (xA,yA) and (xB,yB), and calculate the distance between from city A to city B? Note: Use the distance between points formula dist=sqrt(pow((x2-x1),2)+pow((y2-y1),2)) Input and Output Format: Refer sample input and output for formatting specification. All float values are displayed correct to 2 decimal places. All text in bold corresponds to input and the rest corresponds to output. Test Case 1 Input (stdin) 12 33 13 4 Expected Output The distance between two points is=29.02 units Test Case 2 Input (stdin) 7 6 2 3 Expected Output The distance between two points is=5.83 units

Program :

#include <stdio.h>

#include<math.h>

int main()

{

  int x1,x2,y1,y2;

  float r;

  scanf("%d%d",&x1,&y1);

  scanf("%d%d",&x2,&y2);

  r=sqrt(pow((x2-x1),2)+pow((y2-y1),2))

  printf("The distance between two points is=%.3f units",r);

return 0;
