Question#1:

find the errors, and why?

rec_sqr.h

class Rectangle

{

private:

public:

float length;

float width;

Rectangle(float l,float w);

void setlength(float);

void setwidth(float);

float perimeter();

float area();

void print();

friend void isSameArea(Rectangle , Square);

};

//--------------------------

class Square

{

private:

const float side;

Square(float s);

float perimeter();

float area();

void print();

friend void isSameArea(Rectangle , Square);

};

//-----------------------

friend void isSameArea(Rectangle rec , Square sqr);

rec_sqr.cpp

#include<iostream>

using namespace std;

Rectangle::Rectangle(float l,float w)

{length=l; width=w; }

void Rectangle::setlength(float len)

{ length = len; }

void Rectangle::setwidth(float wid)

{ width = wid; }

float Rectangle::area()

{

return length * width;

}

void Rectangle::print()

{ cout<<length<<endl;

cout<<width<<endl; }

//------------------------

Square::Square(float s)

{

side=s;

}

float Square::area()

{

return side*side;

}

void Square::print()

{

cout<<side<<endl;

}

//-----------------------

void isSameArea(Rectangle rec , Square sqr)

{

if(rec.area()==sqr.area())

cout<<"equal"<<endl;

else

cout<<"not equal"<<endl;

}

main.cpp

#include"rec_sqr.h"

int main()

{

Rectangle rec1(2,8);

const Rectangle rec2(3,4);

Square sqr(4);

rec1.isSameArea(rec1, sqr);

cout<<"rec1:"<<endl;

rec1.print();

cout<<"rec2:"<<endl;

rec2.print();

cout<<"sqr:"<<endl;

sqr.print();

system("pause");

return 0;

}

find the errors, and why?

Explanation / Answer

In square class,all methods are defined private..but later accessed in main function..which is not correct
