A number of posts are pretty adamant that source code should not go in a header and that header files should be kept to a minimum. I've been sticking to this with my own code, but I want to use someone else's code to achieve a particular goal (the code is documented here http://ftp.arl.mil/random/).
I notice that this is basically one giant header file which defines a class. Is it OK to leave this in a header file? Should I copy it all to a .cpp file and create a new .h that just declares the functions, structures etc?
If I split it into a .cpp and a .h as I propose, will it work? Or do classes need to be in the header to be accessed by all source code?
