<0> I could but one, that would certainly never happen in any of our programs in the cl***. Secondly if he retorts with absolutetly anything I have no where to go from there. Thirdly its argueable that its only poor planning that would result in a change.
<1> and also, it's rarely important to know by looking at a name whether it's constant or not
<1> not only "poor planning" far more often a change in scope of the project
<0> lol its also a very good idea to do error checking on things you open and so on and so forth, but we don't have to do that.
<0> Again its convention, there is no truth or falsitity to it. It'd be like argueing that chocolate is better than vanilla.
<0> or maybe in this case that chocolate is better tasting than dog poo.
<1> you don't inData.open(FILENAME); if(!inData)(/* report an error and stop*/}
<0> lol I meant in a more general sense
<0> in this case yes.
<1> well, given that the while loop will not execute, so you'll have 0 entries you'll find out soon enough
<0> look I'm not saying what he is doing is correct, but its a beginning entry level course in to programming.
<0> I know the non C++ aspects of it already
<0> and alot of the C++ aspects
<2> you know, because teaching beginners the wrong way is even better because they don't know it's wrong ;)
<0> you have to tell lies in everything to teach.
<0> Look its not like Tuesdays lecture is going to be Global Variables 101
<0> I'd say 99% of people in the cl*** will never write another program after this cl***
<0> unless they take another programming course that is more advanced
<0> and alot of good programming is learning from your mistakes.
<2> that makes it ok to code wrong?
<0> lol
<0> no I'm just saying that you always have to tell little lies in any cl***.
<0> Whether it be eletron orbitals in Chemistry, or can't square root a negative in Math.
<1> cn28h unfortunately a lot of teachers, I think, actually DO not care beacuse "they'll never write another program after this cl***"
<2> lies are for history cl***
<1> and psychology
<0> lies are for every cl*** when the concepts you are teaching them has nothing to do with the lie, and teh lie makes your life easier.
<2> yeah :/ the one I teach for is kinda that way I think
<0> and I believe that really the only way to become a good programmer
<0> is to be a bad one and learn from your mistakes
<0> Its only after I looked at code I hadn't touched in months
<0> that I decided I'd start actually documenting.
<0> And so on and so forth
<2> don't mistake simplifications for lies, either
<0> hmmmmm well I consider them one and the same.
<2> you don't start out teaching Newton's law of gravitation by explaining to the students that for non-spherical bodies of a non-trivial size that multiple integration is required to find the answer
<2> you start with simpler cases
<2> and work up to the more complex ones
<0> okay and then for C++
<0> what my teacher done wrong
<0> and actually lied about
<2> I don't recall saying your teacher did anything wrong, I just disagreed with the lying thing
<0> well what did he lie about
<0> by your definition of lie
<2> <2> I don't recall saying your teacher did anything wrong, I just disagreed with the lying thing
<0> oh
<0> well
<2> i.e. the "you have to lie to teach"
<0> oh
<0> I meant lie in a stricter sense.
<2> Bill Clinton comes to mind
<0> my physics teacher said nothing about non-spherical non-trivial bodies, we just '***umed' that we could model it.
<0> I would consider that a lie
<2> do you know how to compute multiple integrals?
<0> depends on the integral
<0> I kinda skipped alot of that section of Calc III
<2> heheh
<0> lol
<0> well
<2> well, perhaps you need a more advanced physics cl***
<1> you consider it a like that he forgot to mention that the m*** changes as the speed changes?
<1> err, s/like/lie
<0> in the strictest sense yes.
<1> you're a very strange person
<0> how so?
<0> its not like he hid it from us, its just the model we use doesn't cut it, and he says to ignore it.
<0> and this was High school physics
<0> I haven't taken a university physics cl*** yet
<0> What would you call eletron orbital diagrams in Chemistry 11 anything other than a lie?
<0> or my math teacher stating 'you cannot square root a negative number'.
<0> those are lies.
<0> that are told to aid our understanding and can be properly addressed later.
<0> its easier to lie than say
<0> "Well even tho you don't know what a real number is, you can square root a negative only the result leaves the real number line and enters a plane that consists of a real and imaginary part, otherwise known as the twilight zone"
<2> but somtimes you can't take the square root of a negative number
<2> it depends on the Field you are working in
<2> if you consider only reals, then square root of negatives are undefined
<0> Field? You mean the scope or usefulness of the answer?
<0> that is a very poor way to write what I meant.
<2> http://mathworld.wolfram.com/Field.html
<0> okay thats above me
<0> The point is that my High school teacher left me with the distinct impression that you CANNOT square root a negative number
<0> that is a lie
<1> not in the domain of reals
<0> yes it is a lie because nothing of domain is mentioned.
<2> you never learned about domain and range? some high school math cl*** you had heheh
<0> lol I did
<1> this was 1st year algebra, right?
<0> okay this isn't a deposition
<0> I can't remember which teacher told me what.
<2> :)
<0> Alls I am contending is that as a regular occurance students in highschool are told that you cannot square root a negative
<1> that was like 45 years go
<0> This probably would have happened when you learnt the square root operator
<2> and in those cases, it's true
<0> hmmmmm
<2> because in those cl***es you don't consider complex numbers
<0> right but the actual general cl*** of square rooting a negative is false
<2> that's the great thing about math, you can just keep generalizing things
<2> but it doesn't mean the less general case is wrong
<0> just like if I am looking at a function of a population and its derivative. I make the function contineous upon reals, but the cl*** is only useful for Integers.
<0> Okay so if I'm trying to find the average number of kids a family has and I get a number like 3.8 and round that to 4.
<0> I can say that 4 is the average
<2> nope
<0> but in the general case of just numbers that is incorrect.
<2> 3.5 is the arithmetic mean
<2> that just means the practical averages is 3 to 4
<1> one hopes ... the word "average" is SO imprecise
<0> fair enough vawjr
<0> cn28h okay so if I take my Calculus I book and open up to a problem that is only useful for discrete numbers, you are saying that those less general cases are just as correct as the general ones.
<2> you have discrete math in your calculus book?
<0> no I meant discrete numbers as in problems for discrete objects.
<0> I have calculus in my discrete math book actually
<0> but thats besides the point.
<2> I'm really not sure what you are getting at
<0> Hmmmmm
<0> Its 4 am
<2> it's almost 7 am here
<0> and I'm splitting hairs over definitions
<2> heheh
<1> coming up on 5 here
<2> I've been writing a math lab all night
<0> we are arguing and debating over sloppy language and misintepretations.
<0> I'm finishing this last ***ignment
<0> and e-mailing it to my prof
<2> we are debating your claim that "lies are necessary to teach"
<0> for
<0> lol and the debate is coming from what I mean by lie being different from what you inteprete it as.
<2> you have a very strange definition of lie, apparently heheh
<0> lie - Something meant to deceive or give a wrong impression.
<1> cn28h Amen Bro!!
<2> heheh :)
<1> SJr|nx__ that _could_ be the truth
<2> so your high school teachers meant to screw you over by telling you couldn't take the sqaure root of a negative number?
<1> SJr|nx__ do know the best way to lie?
<0> lol no
<0> lying doesn't by definition imply that someone is trying to screw you over.
<3> parents do it all the time :P
<3> *yes, santa is real*
<0> To cause to believe what is not true; mislead.
<0> To give a false impression
<3> *you will grow an apple tree in your tummy if you eat apple seeds*
<0> yes thank you Tamama
<0> I have been getting destroyed by these two
<3> They are good at it
<1> SJr|nx__ that you chose to believe that "you cannot take the square root of a negative number" to apply outside the domain you were studying seems like a PP to me, not a lie.
<0> PP?
<1> Personal Problem
