<0> rdragon yep
<1> i just didn't understand why ones had to be overloaded an how for what i was doing, if i made a list of employees as apposed to string
<2> the Bresenham algorithm is good for that
<0> rdragon from what I read, that's what this one is based on
<3> Jazy84 i have no idea what you mean by that
<2> Graveling it doesn't look like it
<1> http://www.noidea128.org/sourcefiles/16121.html
<2> oh actually, maybe it does
<3> Jazy84 you're writing your own hashtable?
<1> yes
<2> except that this only handles drawing when deltaY > deltaX
<3> another teacher that want's to re-invent the wheel
<3> <sigh>
<0> that one I have the link above for seems to only create a line in a positive gradient. I have to be able to click on two points on a screen and draw a line between them
<2> okay
<2> then...
<3> Graveling why not plot the middle point, then call yourself twice with one end, middle and middle other end
<0> hmm
<3> no need to check for quadrants, or which is larger, etc
<0> the main problem I am having is that it will only plot directly in one direction. I cant seem to see whay
<0> err, why
<3> presuming that a.x+b.x)/2
<3> aargh
<3> presuming that (a.x+b.x)/2 doesn't overflow
<4> and if its plottable on the screen, it liekly won't :)
<4> untill you do conversaion to screen coordinates part
<0> I can get it to plot a line in +x, but only between 90 and 135 degrees
<2> Graveling take a look: http://www.noidea128.org/sourcefiles/16122~
<2> it can be made a bit more efficient with pointer arithmetic, but there's the general idea
<2> you might also check to clip the points
<5> Did you see my earlier rant vawjr?
<0> ok
<5> hmmm, guess you're not here. heh, oh well.
<2> Graveling the algorithm has to be split up depending on the slope of the line
<2> because you want to iterate over the axis that only has 1 pixel per row (or column)
<2> to draw
<2> then for each iteration, you can decide whether you need to move up/down a pixel on the other axis
<2> the numbers are blown up here to work completely with integer arithmetic
<1> friend ofstream& operator<<(ofstream& to, Employee &what) {
<1> to<<what.name<<" "<<what.id<<" "<<what.dept<<endl;
<1> return to;
<1> }
<1> what is wrong with that?
<2> you can't define something where you're declaring it 'friend', I don't believe
<3> Jazy84 Employee const &
<3> and why must it be inside the cl***? (no real problem doing it that way, but why?
<2> ah, k
<3> Noidea no, I don't think so...do I really want to?
<2> defining it like that within the cl*** makes it a free function?
<1> doesnt' have to be :)
<3> rdragon I guess so, why?
<6> Were you around for the other night's discussion of California's elephant protection law, vic?
<3> no, and I'm glad I wasn't
<2> wasn't sure if that was legal or not
<6> Only if it doesn't harm an elephant in California
<1> darn i still get 2 errors
<2> struct A{ friend void f(){} }; int main(){ f(); }
<2> vc8 complains that the candidates for 'f' are inaccessible
<3> huh??
<7> eh?
<3> Jazy84 I can't read your mind tonight... what errors?
<1> hold up
<3> http://www.nytimes.com/2006/04/04/us/nationalspecial3/04scotus.html?ei=5094&en=4bb297bacb8e14d3&hp=&ex=1144123200&partner=homepage&pagewanted=print
<3> oh ****, this court isn't any better than the previous 6 or 7
<1> http://www.noidea128.org/sourcefiles/16123.html
<2> 10000 lists? yikes
<4> haha, thats what I said.
<2> **friend <-- huh?
<3> #include <fstream>
<3> but that's likey NOT what you want
<2> are you sure you want it to be an ofstream and not simply ostream?
<3> you likely want ostream
<8> hi
<8> is float arithmatic faster than double?
<3> dextre1 depends on the machine
<2> Jazy84 I think you're going to run into another problem after you fix that, too
<8> arithmetic.. on a pentium
<3> I don't know, and I don't care
<4> hehe
<2> dextre1 why don't you just try it out and see?
<3> it's irrelevant to C++
<8> ok
<2> get a stopwatch, and run your program, then change the code and time it again
<3> and all you'll find out is if it's faster on YOUR machine
<1> alright if i add ostream
<2> Jazy84 you changed the return type too, right?
<3> oh and put it in Employee, not hash2
<2> er, yeah
<1> both to ostream right?
<2> ...yes
<2> 10000 member list objects isn't a great idea, idea
<2> neither is using character pointers as strings
<2> neither is using a signed type to represent size/length
<2> neither is instantiating an iterator object, and then using indexes on the next line to iterate
<2> neither is this loop: for(int i = 0; i <= keyLength; i++) which oversteps the bounds of the 'string', which is why you should be using real strings
<2> neither is having three 'setXXX' functions, when the member they set is public
<3> gonna call it quits, I'm somewhat under the weather today
<6> Night, vic
<1> quick question
<1> Employee& operator==(Employee const & what);
<2> no
<1> i'd want to use something like that to overload ==
<2> == should return true/false, come on
<1> opps the =
<1> rather
<2> okay, then yes
<9> Hello
<2> you should also remember to check for self-***ignment in that function if( &rhs == this ) return *this;
<1> but now that we are talkinga bout == i'm checking it by an *iter==item
<9> I can return error with extended information from ATL DLL using this kind of thing .. >> return Error("Wrong number!", GUID_NULL, E_INVALIDARG);
<1> now in the overloaded== what should i compare?
<2> you should check for equivalence
<9> What if my function is a void function and not STDMETHODIMP
<9> ?
<2> or maybe you check for equality... I guess it really depends on the design
<1> lets say i wanna check an input string for equivalence on one of the strings in my cl***
<2> if( str1 == str2 )
<1> will something like this work
<1> bool Employee::operator ==(const string &what) {if (what = this.name)return true;else return false;
<2> return( what == this.name );
<1> error C2228: left of '.name' must have cl***/struct/union type is 'Employee *const
<2> duh
<2> return( what == name );
<2> you wrote this. and I pulled a JBlitzen and retyped it
<1> ah don't need the ****
<1> this*
<2> ;)
<6> Don't make me abuse you with block and tackle
<6> I might make that my next slap message
<2> heh
<2> oLDmeMoRy don't private message me
<2> ask in channel like everybody else
<6> You ever play Shadow of the Colossus again, rd?
<2> yeah I still do
<2> haven't beaten it yet
<2> I think I have 3 or 4 more colossi to go
<2> i hate the ones that shoot back, lol
<6> Nice
<2> but the last 2 I fought were pretty creative
<1> http://www.noidea128.org/sourcefiles/16124.html
<1> can you take a look at my search function
<2> how about you put a break; after found=true;
<2> or better yet
<2> return
<2> why are you comparing Employee 's to strings ?
<2> and you should p*** that string in by const reference
<2> and why is key a const char* and not a string?
<2> and why don't you just use a std::map or something?
