I haven't really seen flow-charts used in books or elsewhere since about the late 1970s - early 1980s. They can still be used to model small sections of software prior to making pseudo-code of the same thing. I'd consider the use of pseudo-code as the modern-day version of flow-charts. Anything that provides a 'mind-picture' of what the program does is useful. By all means, show that flow-charts exist. Some students will find them more useful than other students will. And show that other ways of seeing the same thing exist too.
