In-place removal is definitely one possibility. See this[^] link for more information. Alternatively, you could walk the source vector and copy non-duplicates to a target vector. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com

it isn't safe for linux to allow that actually. imo what vc++ did is correct. anyway if u want a zero-sized array, do u mean u're going to allocate memory to the array on the fly? if so, u should declare it as a pointer. i.e. T *ptr; then u should use new and delete to alloc and free the memory respectively. even better, use vectors as it does all the memory handling for u. http://www.roguewave.com/support/docs/sourcepro/stdlibref/vector.html[^]

What do you mean, "wont recognize the header files"? Do you mean that it reports them as not found? If so, then you will need to either (a) change the project settings (Project/Settings, C++ tab) category 'Preprocessor', add folder containing wxWindows headers to the 'Additional include directories' box. or (b) Add the appropriate directories to the system-wide settings Tools/Options, directories tab. You will probably also need to add the lib folder too, unless wxWindows is purely template based (like WTL), or you'll get link failures. If you go for option (a), remember to do this for ALL targets, not just Debug or Release, or when you build different versions, you'll have to do it again! Hope this helps Steve S Developer for hire

I'm not making his homework. I just give him a sample skeleton, not the solution. Sure I know a way to find out if it is a prime or not, I've done that before. But if you can't think of one by yourself, you just have to take math classes.
