5-10. a. Modify the rectangle class from 5-8b (shown at the bottom) so rectangles can be added or subtracted by overloading the + and - operators to mean adding or subtracting the lengths and widths.

b. Modify the rectangle class again so rectangles can be compared by overloading some of the comparison operators (=, !=, <, >, <=, >=) to compare the area (or perimeter). Overload the operators used below.

Use the following ex5-10.cpp and create the corresponding rectangle5-10.h header file. Overload the operators used below. Add documentation. Submit the rectangle5-10.h /*
