Hello,
One quick question. Is it better to assign array size , especially when its large such as a[30000], during compile time or run time inorder to make it run fast? Well as far as i know the latter one is preferable, but i just used the Profiling Tool and found out that the new[] and delete[] operators consume some quality time especially when it runs in a loop of say 30000! So can somebody please help me out?
thanks,
prads

It depends on how the array is being used. If the program will never get anywhere near the array maximum, then you should have input to deterime the proper size (i.e. dynamically). Especially if the array won't be filled or close to it, it would be wasting memory...
