Q:

where can I find the .cpp file in CGAL?

I download the source code of CGAL in Github, but I just find the .h file,no .cpp, where can I get it? cause there is only declaration of function in the class of .h, but i want to see the source code of the function.
Thanks. 

A:

There are almost no .cpp files in CGAL. It is a libary just as Boost, that is it is header only.  This means that what you call "the source code" is template code which is in the header files. Sometimes you have to dig a litte bit deeper, that is the code is in another header files that gets #included.
