Question

In this exercise, you will write a Point structure that represents a space in two-dimensional space. This Point should have both x and y elds (please use these exact names). You will also write three functions for dealing with Points; freadPoint, manhattanDistance, and euclideanDistance. freadPoint should take in a FILE handle and a Point (by reference) that it will initialize; it should not do any prompting. It will return true if it succeeds in reading a point and false if it fails. Each point will be a line in the le, with the x and y coordinates separated by spaces. A sample input le, point29.txt has been included. The manhattanDistance function will take two Points and compute the Manhattan distance (city block distance) between them, which is the distance that you would travel if you are restricted to walking parallel to either the x or y axes. Likewise, the euclideanDistance function will take two Points and compute the Euclidean distance (straight-line distance) between them. Neither function prints anything; they simply return a value. Your main function will prompt the user to enter two points and then display the Manhattan and Euclidean distances. You should call each of your functions (using stdio as a parameter to freadPoint) to do so. You may want to use the fabs and sqrt functions to help you with this assignment

Answer 1

Answer:

Check the explanation

Explanation:

Points to consider:

We need to take the input from the user

We need to find the manhatan distance and euclidian using the formula

(x1, y1) and (x2, y2) are the two points

Manhattan:

$|x_1 - x_2| + |y_1 - y_2|$

Euclidian Distance:

$\sqrt{(x1 - yl)^2 + (x2 - y2)^2)}$

Code

#include<stdio.h>

#include<math.h>

struct Point{

  int x, y;

};

int manhattan(Point A, Point B){

  return abs(A.x - B.x) + abs(A.y- B.y);

}

float euclidean(Point A, Point B){

  return sqrt(pow(A.x - B.x, 2) + pow(A.y - B.y, 2));

}

int main(){

  struct Point A, B;

  printf("Enter x and Y for first point: ");

  int x, y;

  scanf("%d%d", &x, &y);

  A.x = x;

  A.y = y;

  printf("Enter x and Y for second point: ");

  scanf("%d%d", &x, &y);

  B.x = x;

  B.y = y;

  printf("Manhattan Distance: %d\n", manhattan(A, B));

  printf("Euclidian Distance: %f\n", euclidean(A, B));

 

}
