For long time, I know I should read this book. This time finally I read Effective STL by Scott Meyers. Allocator is way to difficult for me, but others, like usage of remove() and erase(), algorithm's topics are quite interesting and useful. Highly recommended.
Here is my question. The area of parallelogram is the difference of these two rectangles (red rectangle - blue rectangle). This is not intuitive for me. If you also think it is not so intuitive, you might interested in my slides. I try to explain this for hight school students.
