Thread: Slow boards

If things don't start picking up soon I'm going to pass out programming assignments to everyone.

No, I'd give out problems that would ensure more traffic in the C and C++ forums.

Salem (I think) already beat you to it a couple of days ago with:

But that's the closest to a cry for help that i've seen from a programming addict.

edit: I think Stoned_Coder may have mentioned this one occasionally, too:

Ok here's one, HOW DO YOU EXTRACT INFO FROM A DATABASE W/O HAVING ACCESS DIRECTLY TO THE DB?? THE ONLY ACCESS YOU HAVE IS A WEB FORM(SEARCH FORM)....

That's an assignment I just got from my boss... I have to EXTRACT the info from that DB and put the results into our own DB... cool huh

Feel free to use PHP or PERL/CGI and of course XML... thank you

if you think this is a slow board, you should see the wookie's message board... it went from over a million to less than 20k in less than 6 months...

He's been giving that link out for years now.

Anyone given out http://ace.delos.com/usacogate/?

haha yes fragblast is dying. but the 4 day break i will work on the battle system alot

unless the posted problem set gets in my way..YAY! PROBLEM SET! woo! lol

Prelude, wanna search for a bug in my Expression Manipulator program?

From the cprog file archives (the same attached file I posted before, if you already have that)

Here's the nature of the problem:
Sometime when using the evaluate_func() function in expression.cpp (or functions called by that function), a reference gets passed which is invalid. I know this because a typeid() of it crashed the program.

If you're interested, I'll post more details about where the bug is located, and some updated code.

//edit: Just clarifying, the link is just to give a general impression of the bug... any bug-finding should be done with newer code.

Or you could advertise on other webpages, however that does cost money.

haha... no wonder why things take so long to get done... ;-)

You want some action Prelude, tell me how the hell to use the value_comp function for associative containers. I've searched all over google and I get plenty of pages that mention it, but not one of them I have seen so far has any examples of usage for this function. It would seem that you could (maybe?) use this to iterate through, let's say a map, according to the order of the values and not the keys? But how does it work?

>Prelude, wanna search for a bug in my Expression Manipulator program?
I'll take a look at it.

>You want some action Prelude, tell me how the hell to use the value_comp function for associative containers.
It returns a constant for the container that gives you the comparison function object. The default is std::less:

Code:

#include <iostream>
#include <set>

int main()
{
    std::set<int> s;

    std::cout<< typeid(s.key_comp()).name() <<std::endl;
    std::cout<< typeid(s.value_comp()).name() <<std::endl;
}

Basically, key_comp and value_comp are observers; they give you information about the container, but don't effect any change.

gotw #87 should keep you amused for a while prelude. There could be some interesting discussion on the dependant/non-dependant names issues arising from the standards looseness on this issue.
