In lecture today, a number of topics were covered, all under the general idea of “operator overloading” for classes:
- the idea of operator overloading for classes
- the notion of operator?? methods being built into our classes
- the syntax for operator overloading in .h and .cpp files
- the notion that we must choose semantics (meaning) for operator overloading (sure, I can use == on Rectangles, but what does that mean w/ respect to Rectangles?)
- the this keyword
- the notion that operators should allow symmetry when possible
- the definition of friend functions
Here is the Rectangle class we have built so far: Rectangle.h, Rectangle.cpp, rectangleMain.cpp. These files can be compiled using the following syntax (if not using a makefile): g++ -o rectangleMain rectangleMain.cpp Rectangle.cpp
Since a lot of material was covered today, here are some slides that cover the key points: OperatorOverloadingI.pdf
A new homework (#4) will be posted soon and be due the middle of next week.
