Question

Start by using the starter code provided for the Line class. It implements operator overloading so you can use cin/cout with line objects.

A line will be made up of two points.

Create an object to implement a “line” class which allows the programmer to store a line. This class must use the “point” class developed in Part B. The object should have two constructors, appropriate set/get functions, and overloaded I/O (cin/cout) functions. It should include functions the return the proper value for the following:

• Determine the slope of a line

• Determine the length of a line

• Determine the y-intercept of a line

• Determine if the line is vertical

• Determine if the line is horizontal

• Determine if the line is parallel to another line

Please create proper test cases for this in main() to verify proper functioning.

Note: You should make it easy on yourself and use four integers representing the two ends of the line for the second constructor

Starter Code:

#include <iostream>
#include <string>
#include <vector>
#include <cctype>

using namespace std;

// Please complete this Point class.
// The cin/cout operators have been overloaded for you
class Point {

// cout implementation for Point class
friend ostream & operator<<( ostream &output, const Point &P ){
output << "x: " << P.x << " y: " << P.y;
return output;
}

// cin implementation for Point class
friend istream & operator>>( istream &input, Point &P ){
input >> P.x >> P.y;
return input;
}

public:
Point(){
x = 0;
y = 0;
}

Point(int in_x, int in_y){
x = in_x;
y = in_y;
}

// Add your functions here
private:
int x,y;
};

int main(){
Point P1;
Point P2(7,6);
cout << "Point P1 should have 0,0 as values" << endl;
cout << P1 << endl;
cout << "Point P2 should have 7,6 as values" << endl;
cout << P2 << endl;

cout << "Enter x and y points: ie 3 4 ";
cin >> P1;
cout << P1 << endl;

return 0;
}

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
