you pronounced them the wrong way round.

The words routine, method, and procedure are not used by Stroustrup in connection with subroutines. The only word he uses in this regard is function. You can check this by looking in the index to The C++ Programming Language. You can look at the specs for other languages to see what is correct for them.

That is also true of B and C, going by early Bell Labs documents that are available online.

People use these words interchangeably. It confuses students. How would you define them? How do they differ?
Routine, n., a set of instructions executed to perform a specific task. Subroutine, n., a routine invoked in some fashion from another routine, with a mechanism to return control to the calling location when the subroutine has finished. Subroutines may be referenced by address, line number, or a symbolic name depending on the language and system in use. Procedure, n., see Routine Function, n., a subroutine, invoked by name, that returns a value but does not otherwise alter the state of the system. Also another name for a subroutine in C and C-like languages. Method, n., in Object-Oriented Programming: a subroutine, invoked by name and context (object). Methods are generally used to retrieve information about the context object, or to modify it in some way, although they may do neither, instead acting as functions (in OO systems that do not provide a means of defining functions, this practice may be used to simulate them).

Been eating lots of beans today, I see.
No, as others have said, a method, and a procedure are the same thing. Even a function is the same thing, if it's inside a class, it's a *member* function. And a routine, I've not heard them called that by anyone for a long time.

And nude and NAKED
Yeah, naked requires an observer. You may be sunning yourself nude in your backyard and suddenly find yourself naked when a neighbour greets you over the fence.

My Performing Arts prof would argue differently :) He'd say that a nude figure is objectified. Not that I agree with much of what he says...

Not different at all as all the others have said.

For me, it's programming language dependent: Routine: Only for assembly language, FORTRAN, and command line batch files. Yes, I consider batch files programming, at least for purposes of this discussion. Method: C++ functions within a class, or COM methods within an interface. I don't C# (I'm near-sighted) or Java, but I imagine they're equivalent. Procedure: Pascal or Ada; any language that distinguishes between routines that return a value and those that don't. Procedures don't return a value, and can't be used on the right hand side of an assignment. Function: C/C++, or any language where a piece of code returns a value that can be used in a right hand side expression.

I skipped that entirely. Thankfully.
