Try something like: struct WorkUnit { ... }; Replace all of the above code by providing an appropriate default ctor, copy ctor and op== for class/struct WorkUnit. And do as follows: #include <vector> int main() { std::vector< WorkUnit > v(100); // done, 100 WorkUnits } Just in case you fail to see the light: #include <vector> #include <string> int main() { // 1000 doubles all initilixed to 1.1 std::vector< double > vd(1000, 1.1); // 100 strings all initialized to 'default' std::vector< string > vs(100, "default"); } Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
