Exercise L2-1 Chap 13 Overloading and Templates
Please ensure your class header files have the exact same function names as listed below.
If your class definitions do not match, I will be unable to test them. When submitting
your lab assignment submit only the .cpp and .h files you created or modified. Be sure you
have coded the cout statement as described in the Grading Rubric inside the contructor.
In this exercise, first redefine the class rectangle Type by declaring the instance variable as protected and then
overload additional operators as defined in parts A through C.
A. Overload the pre- and post-increment and decrement operators to increment and decrement, respectively,
the length and width of a rectangle by one unit. (Note that after decrementing the length and width, they
must be positive.)
B. Overload the binary operator - to subtract the dimensions of one rectangle from the corresponding
dimensions of another rectangle. If the resulting dimensions are not positive, output an appropriate
message and do not perform the operation.
C. The operators == and != are overloaded by considering the lengths and widths of rectangles. Redefine
the functions to overload the relational operator by considering the areas of rectangles as follows: two
rectangles are the same, if they have the same area; otherwise, the rectangles are not the same. Similarly,
rectangle yard1 is greater than rectangle yard2 if the area of yard1 is greater than the area of yard2.
Overload the remaining relational operators using similar definitions.
D. Write the definitions of the functions to overload the operators defined in parts A through C.
E. Write a test program that tests various operations on the class rectangleType.

double area() const;
double getLength() const;
double getWidth() const;
double perimeter() const;
void setDimension(double I, double w);

Follow-up Question

Hey thank you for your answer.

I would like to know the main C++ modules that I need to know/understand to complete this program myself. i.e (Classes, structures, arrays, strings...)

Please let me know the exact modules so I can study them as soon as possible.

Thank you.
