how many times in your life have you implemented recursive methods
-
I can count with the fingers of my hand the times I had to implement recursive methods in my life, so what was the fuzz all about when you are in school ant programming teachers tell you that that is the holy grail of programming!!! ps: i know that is important but most of recursive functions are implememnted and you only have to use them.
not many. a dozen maybe. but it's good to know how to do it. when the situation arises and you need to get recursive, it helps to have done it before, because it can be a little tough to get your head around it sometimes.

Often enough, they come in handy when working with trees and graphs*, but of course I didn't have to, I might just as easily have written them with an explicit stack. They are, of course, not the holy grail of programming. * contrary to popular belief, they actually are used outside of academia.

I agree, I still remember the smoke coming out of my classmates ears the section we were doing recursion in c++. course, come to think of it these were the same guys that responded with an answer of a "if" when asked what kind of loop they would use in "x" situation....... :doh: Thought my poor instructor was going to have a stroke on the spot. This was not in the beginning course either, it was in data structures. (3rd course in c++ for us, beginner, advanced, then data struct.).
Common sense is not a gift it's a curse. Those of us who have it have to deal with those that don't.... Be careful which toes you step on today, they might be connected to the foot that kicks your butt tomorrow. You can't scare me, I have children.

Quite often, recursion is very handy.

Lots!! If you use Prolog or any of the functional languages, it's extremely useful, fast and efficient to use (tail) recursion. In fact, I can hardly imagine programming anything in those languages without recursion.

ahahaha , that was a very good joke I understood it when I clicled at the link nice man!!

Just make sure you get paid for number of lines executed instead of number of lines written! :thumbsup:

I've done it a few times...but who really needs to learn about them are the people who write the instructions on shampoo. I get stuck doing lather, rinse, repeat until I stack overflow because they forgot an end condition...

I imagine some developers come across recursion more often than others. For example, I sometimes deal with recursion when writing code that traverses the file system, but I don't do that very often. Video game developers might do it when they handle BSP, closest path algorithms, collision detection, and so on. And just because you don't use it often does not mean it's not incredibly useful. Some problems might seem insurmountable without recursion. You might also seldom use trigonometry, but when you need it you really need it.

Hate prolog at so many levels that I thank god I dont need to use it in my normal life

Linear algebra is another one. Don't use it at all for most things, but good luck doing 3D graphics without it. It's good to have a varied tool kit, just in case.
I don't get to use that very often, as I took a class called "Linear Algebra" in college and now I have no idea what linear algebra is. :)
