Question

17.11 Worksheet 9A

Point
- x:double - y:double
+Point() +Point(x:double, y:double) +setPoint(x: double y:double):void +setX(x:double):void +setY(y:double):void +getX():double +getY():double +findDistance(Point point):double +print():void

• Create a class called Point as described below
• Constructor with no arguments
  • Sets x to 0 and y to 0
• Constructor with arguments
  • Sets the x and y to the values passed in
• Get methods (accessors) return the field that the get refers to
• Set methods (mutators) set the field to the new values passed in to it
• The print method prints the following for the point (3.54, 5.43).

           The point is (3.5, 5.4).

Below is main.cpp - follow the instructions in the comments

#include <iostream>
#include <string>
#include <cmath>
#include <fstream>
#include "Point.h"
using namespace std;

void loadArray(Point points[], int& numE, string filename);


int main() {

    Point point1 = Point();
    Point point2 = Point(1, 0);
    Point points[50];
    string filename = "points1.txt";
    int numE = 0;
    double totalPoint1 = 0;
    double totalPoint2 = 0;

    loadArray(points, numE, filename);

    totalPoint1 = findTotalDistance(points, point1, numE);
    totalPoint2 = findTotalDistance(points, point2, numE);

    cout.setf(ios::fixed);
    cout.precision(1);
    cout << "The total distance from point 1 to the points in the array is " << totalPoint1 << "." << endl;
    cout << "The total distance from point 2 to the points in the array is " << totalPoint2 << "." << endl;
}

void loadArray(Point points[], int& numE, string filename) {
    ifstream fin;
    double point1;
    double point2;
    numE = 0;

    fin.open(filename);
    if(fin.fail()) {
        cerr << "File failed to open" << endl;
        exit(1);
    }

    fin >> point1;

    while(!fin.eof() && numE < 50) {
        fin >> point2;
        points[numE].setPoint(point1, point2);
        numE++;
        fin >> point1;
    }
}

// Write a method called find total distance that finds the distance from a point to every other point in the array. 
// It should return the total of those distances.
