Getting ready

The source code we will compile is one of the examples for the filesystem library provided by Boost to interact with the filesystem. This library is conveniently cross-platform and abstracts the differences between operating systems and filesystems into a coherent, high-level API. The following example code (path-info.cpp) will accept a path as an argument and print a report about its components to the screen:
