hello folks,
i've been trying to run the vector example off this site. I've cut and paste it into a Dev-C++ cpp file, then used Borland to compile it, but it's just spat it back out... is there anything else I need to do?
check out the tutorial for vectors from here... that's the one. Anything else I need to run it?
what were the errors? Maybe Dev-C++ doesn't have some of the libraries.
There do appear to be problems there. First, there is no...
using namespace std;
... after the includes, put that in, that'll get rid of most of the compile errors. Second the line...
example.switch(1, 2); //Switches elements 1 and 2
... comment that out. Switch is not implemented on all compilers, in fact, I cannot find it in my copy of the standard! I'm looking into this, sorry for the inconvenience.
Sorry, that was me. For some reason the board logged me out.
mkay... trying it now. cheers.

*** 6 errors in Compile ***
Bleaaarggh! Hmmm,
>>> Dev-C++ cpp file, then used Borland to compile
... I don't use either, I just put it through MS VC++ 6 and it compiles and runs fine. (It doesn't swap of course but otherwise works as described).
The errors look like they are objecting to something in the overloaded stream insertion operator which is part of the class, and hence, not under your control.
More info... exactly what compiler is this? The Borland 5.5 command line freebie?
