Either you have to push_back() items into it, or resize() it, or construct it with the appropriate constuctor: vector <int> tmp(initial_size); Aug 20, 2010 at 10:53pm ne555 (10692) You don't have enough memory. Is it necessary the copy to tmp? You could reserve at the beg...

First getting data from the output, then clearing it and setting it anew? out_data is where you should put the sequence data you newly create, you should never use it as an input!So you have to create a new handle with the appropriate seq data size, lock the handle and fi...
b) The std::fill algorithm that Alf showed. You could also: unsigned s = vec.size(); vec.clear(); vec.resize( s ); Ivan Novick #6 Jan 20 '07, 06:25 AM Re: how to initialize std::vector? Victor Bazarov wrote: JDT wrote: >Can someone show me how to set any integer (or...
