In this video we'll talk about C++ libraries on various operating systems. Libraries are archives of pre-built code that you can use in your own application by "linking" with them. Libraries can be "static" (incorporated directly into your program when you build it) or "dynamic" (loaded by your program when it runs).
Different operating systems have different ways of handling both kinds, but Windows and UNIX-style libraries are the two main types. The Mac adds its own unique variety, but fortunately UNIX-style works on the Mac too.
