IO 4

• Problem 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.

• CODING ARENA

• #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;

  }
