Assignment 03

CSIS 250 2002 Spring	Assignment 03
Date Assigned: 03/01/2002	Date Due: 03/08/2001

Add the following member/friend functions/operators and corresponding test functions to the CRectangle implementation (crect05.cpp) as discussed in the class.

§ int area(void);
to calculate and return the area of a rectangle

§ bool operator < (const CRectangle &rec2);
to compare the areas of two rectangles

§ bool operator <= (const CRectangle &rec2);
to compare the areas of two rectangles

§ friend istream & operator >> (istream &bob, CRectangle &rec);
extraction operator for CRectangle type

§ void testArea(void);
to test area function

§ void testOperatorLessThan(void);
to test operator <

§ void testOperatorLessThanOrEqualTo(void);
to test operator <=

§ void testOperatorExtraction(void);
to test operator >>

For each function, include detailed documentation as mentioned in the class, and properly indented source code.

Submit the following:

§ Printed source code of the working program (to get any credit the program has to work)

§ Printed output

§ Self-evaluation table (will be posted later on the Web)

The main driver should be as follows:

void main(void)

{

srand(time(NULL));

testArea();

testOperatorLessThan();

testOperatorLessThanOrEqualTo();

testOperatorExtraction();

}

The output from the program should be similar to the following:

==============

test area(rec)

==============

rect(1, 9)

Area = 9

------------------

rect(7, 2)

Area = 14

------------------

rect(3, 6)

Area = 18

------------------

rect(1, 8)

Area = 8

------------------

rect(6, 6)

Area = 36

------------------

================

test operator <

================

rec1 = rect(5, 5)

rec2 = rect(8, 2)

area of rec1 = 25

area of rec2 = 16
