<0> anyone ever used the time_t time(time_t *time) function
<1> Whaaaaaaat the hell
<1> Nice BG episode
<2> ugnud yes
<0> well im doing a time(before); running a function the doing a time(after); the doing a runtime = difftime(after,before); and i'm getting a 0 for runtime?
<0> the = then
<2> makes sense
<0> ?
<2> time only tracks things in seconds, iirc
<0> i thought it would break it down more since difftime returns a double
<2> don't know for sure
<0> there has to be a way to compute small times
<2> yeah
<2> I use boost's stuff myself
<3> how dangerous is const_cast?
<2> depends on why you're using it
<2> for dealing w/ legacy (poorly written signatures) code? not at all, you gotta do it
<3> I was thinking about that, like if you use it to un-const the this pointer
<2> geezus, why the hell would you do that?
<3> I wouldn't
<3> I'm just wondering really
<2> every cast is a lie to the compiler
<2> what happens after you lie <shrug> your call
<3> gotcha.
<4> how would I concatenate two c strings?
<5> strcat
<4> i mean, two character arrays
<4> yeah?
<5> A character array is a c-string. Well, if it's null terminated.
<5> But you should use C++ style strings. Because they're better.
<4> strcat(a,b) ?
<0> i need to measure a really small time
<0> how long a function runs
<0> whats the best function
<5> Dunk-: I think so. I haven't used that in years, thanks to std::string. You should do so too.
<4> the system() call requires an old style string, and i am p***ed an old style string from a function
<5> In any case, MSDN holds teh definite answer. I'm pretty sure it's strcat(a,b), but I can'T rememebr which one is concatened to teh other.
<6> Dunk-: std::string x = "Test"; system( x.c_str() );
<6> There's no reason to use old c strings if you are not playing with legacy code
<4> i'd be converting it to a std::string just to concat it, then changing it back
<4> that's wasteful
<6> Dunk-: You should use std::string whenever possible
<6> Anyway ;)
<6> use strcat then
<7> Dunk-, why are you using system()?
<3> Dunk-, <4> i'd be converting it to a std::string just to concat it, then changing it back
<3> so?
<3> You should be aware of the other advantages.
<8> hey what's that c++ tutorial website that we hate the least?
<5> ISn't it the one on About.com?
<8> is it?
<5> Eh, I think.
<2> "That's what we're here for" 1986 Victor A. Wagner Jr.
<2> Solamente says this tutorial isn't too horrible: http://cplus.about.com/od/beginnerctutorial/l/blcpptutorials.htm
<2> sorry
<8> heh
<8> thanks
<7> it's such a pain in the *** to handle them robustly
<2> or just to handle them
<8> or to think about handling them, heh
<7> sometimes it's necessary
<7> but when it's not..;P
<2> brb, gotta reboot
<9> I'd love to know when it is actually necesary
<9> man
<9> just revisited realultimatepower for the first time ina few years
<9> the laughs are just as hard
<2> hmmm, oddness, but Ithink things are back to normal (whatever that is) now
<8> what's back to normal?
<8> or, what wasn't normal?
<2> I installed upgrade to Eudora, it wanted a reboot, ok, ... so it's coming back up and I get a "you need to reboot to finish installing Acrobat upgrade"
<8> heh
<2> I did, and I guess everything's settled, 'cept Eudora is re-indexing all the mails for "fast search"
<10>
<2> I wish I had an ftp program that did downloads like xcopy /D
<7> what does /D do?
<1> [03:33] <peterg> Normally I do not JBlitzen but I bought a really good cpu and it was easy as pie to overclock this CPU from a 2100 to a 2500 in about 30 minutes
<1> [03:33] <peterg> this was 3 years ago
<1> [03:33] <GregE> I overclocked a amd k6III 450mhz to 650mhz
<1> [03:33] <1> What did that enable you to do
<1> [03:33] <GregE> brag
<1> [03:34] <GregE> I dunno
<11> and a less life-span on the cpu
<12> .
<1> :)
<13> what you guys reckon a Data Type for Volst and Ohms?
<13> both double?
<13> is it a good idea?
<13> Volts*
<14> it depends on the operations you want to do on those.
<14> double sounds like a good fit for most applications I can think of.
<15> hi
<15> how do i convert an int to a array of characters in cpp ?
<15> in C, it's sprintf
<15> but in C++ ?
<16> Use std::stringstream and std::string
<15> hmm
<15> ok, thanks
<17> std::stringstream ss; ss << 33; string s; ss >> s;
<15> ok, thanks
<15> 22 C:\Dev-Cpp\md6.cpp argument of type `size_t (std::basic_string<char, std::char_traits<char>, std::allocator<char> >::)() const' does not match `size_t'
<15> now i get that when i wanna do str.length
<17> and the code is?
<18> hey guys. Is somefunction(i++) the same as { somefunction(i+1); i++; } ?
<19> sasder, no
<17> somefunction(i++) == somefunction(i); i=i+1;
<18> aha
<18> okay thanks
<18> and sorry for the noob question :P
<17> somefunction(++i) == somefunction (i+1); i=i+1;
<17> that's how I know it, I may be wrong tho...
<17> :)
<17> you'll have to test it
<15> if (len == 0) len = str.length;
<15> len is a size_t
<15> str is a string
<17> str.length();
<15> oh
<15> thanks
<15> didn't know this is a function
<18> sk8ing: thanx
<17> np
<18> oh... and 1 more question... is there any difference between these two declarations? char* s; or char *s;
<17> no
<18> ok :)
<16> I prefer char* though - keeps the type clearly seperated
<17> it doesn't
<17> char* c, c1; is the same with: char *c; char c1;
<15> it's just same
<16> Yes, but when reading the code, it keeps the type clearly seperated
<16> in theory, char * foo; is valid
<20> char* c, c1; <- i prefer this way...
<16> char* foo; maintains the "type[space]variable" readability
<17> and c1 will be?
<17> I use it like char *c;
<14> Cantide: I would fire you for writing that line.
<17> char *c, c1; it's way clearer than what you've wrote
<17> a begginer might think that c1 is a pointer too
<17> so the type is not char*
<14> Well, I'd fire you for that line as well :P
<17> it's char
<20> >_
<20> >_<
<15> if (sk8ing.infire) sk8ing.infire=0;
<17> :)
<20> heh
<17> sk8ing.infire^=sk8ing.infire;
<17> faster :P
<14> Seriously, defining objects of different types within one line of code is a bad idea. It's also a very bad idea to leave pointers uninitialized.
