C++ PROGRAMMING

please help within an hour so i can give 5 stars :-)

(looks hard but its easy only a couple lines of code need to be implemented)

Related math background: The equation of a line: ax+by c is the standard equation for a line, where a and b cannot both be zero, and where a, b, and c are real numbers. Question Download lab15.cpp from the blackboard. In this file, the definition of the class lineType has given which represents a line equation. In this lab, you are asked to complete the body for two operators overloading function as following: 1) overload the stream extraction operator for the input stream. The user input should be in (a,b,c format where Xcoef a, Ycoef b and ConstTerm c variables for the line object. For example, the code cin line: should accept (2,3,4) as the line input format. 2) overload the assignment operator to assign a line object into another line object. It will copy all member variables from its right operand to its left operand For example, linel line2; will copy all member variables from line2 to the linel object Then, without changing the main function, execute your program to get the same output. Submit a single cpp file.

Explanation / Answer

#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;

class lineType
{
        //Overload the stream extraction operators
        friend ostream& operator<<(ostream&, const lineType&);
        friend istream& operator>>(istream&, lineType&);

public:
        const lineType& operator=(const lineType&);
        //overload the assignment operator

        void setLine(double a = 0, double b = 0, double c = 0);
        //Function to set the line.

        double getXCoefficient() const;
        double getYCoefficient() const;
        double getCOnstantTerm() const;

        void setXCoefficient(double coeff);
        void setYCoefficient(double coeff);
        void setConstantTerm(double c);
      

        lineType(double a = 0, double b = 0, double c = 0);
        //Constructor

private:
        double xCoeff;
        double yCoeff;
        double constTerm;
};

//--------------------------------functions implementation---------------------------------------

void lineType::setLine(double a, double b, double c)
{
        xCoeff = a;
        yCoeff = b;

        if (a == 0 && b == 0)
                constTerm = 0;
        else
                constTerm = c;
}

double lineType::getXCoefficient() const
{
        return xCoeff;
}

double lineType::getYCoefficient() const
{
        return yCoeff;
}

double lineType::getCOnstantTerm() const
{
        return constTerm;
}

void lineType::setXCoefficient(double coeff)
{
        xCoeff = coeff;
}

void lineType::setYCoefficient(double coeff)
{
        yCoeff = coeff;
}

void lineType::setConstantTerm(double c)
{
        constTerm = c;
}

lineType::lineType(double a, double b, double c)
{
        setLine(a, b, c);
}
const lineType& lineType::operator=(const lineType& otherLine)
{
      
        xCoeff = otherLine.xCoeff;
        yCoeff = otherLine.yCoeff;
        constTerm = otherLine.constTerm;
        return *this;
      
}

ostream& operator<<(ostream& osObject,const lineType& line)

{
        if (line.xCoeff != 0)
                osObject << line.xCoeff << "x ";

        if (line.yCoeff != 0)
        {
                if (line.yCoeff < 0)
                        osObject << "- ";
                else
                        osObject << "+ ";
                osObject << fabs(line.yCoeff) << "y ";
        }

        osObject << " = " << line.constTerm;

        return osObject;
}

istream& operator>>(istream& isObject, lineType& line)
{
        isObject>>line.xCoeff>>line.yCoeff>>line.constTerm;
}
//----------------------DriverProgram-----------------------
int main()
{
        lineType line1(2, 3, 4);
        lineType line2(3, 5, 7);
        lineType line3(2, 3, -2);
        lineType line4(3, -2, 1);
      
        lineType line5;
        lineType line6;

        cout << "line1: " << line1 << endl;
        cout << "line2: " << line2 << endl;
        cout << "line3: " << line3 << endl;
        cout << "line4: " << line4 << endl;
              

        cout << "Input line5 in the form (a, b, c): ";
        cin >> line5;
        cout << "line5: " << line5 << endl;
      
      
        cout << "line5 has been copied to line6 by the assignment operator" << endl;
        line6 = line5;
        cout << "line6: " << line6 << endl;
        return 0;
}

Output:

line1: 2x + 3y = 4

line2: 3x + 5y = 7

line3: 2x + 3y = -2

line4: 3x - 2y = 1

Input line5 in the form (a, b, c): line5: 2x + 3y = 4

line5 has been copied to line6 by the assignment operator

line6: 2x + 3y = 4
