Hi
In the below code , i am getting compile time error when declaring the copy constructor .

Please can anyone help me with clean compilation.

Hi ,

Sorry for the trouble , i realised that dynarray is a memeber of namespace std.

I replaced it with Darray and the code compiled clean .

Thanks

Look very closely at this line dynarray(const [b]dynarrray[/b] &ob); I believe you probably meant to type dynarray instead

No it isn't, the compile error was a simple typing mistake.

Yes you are correct . Thanks a lot .
Actually , while replacing dynarray with Darray i replaced everything manually , so it worked . After ur post i switched all back to dynarray and it works...thnks again
