I also must be showing my age ;-:) (showing the toothless, dentureless smile) Seriously, though the points you make about template classes, along with over use of inheritance, and bulky code in some classes makes C++ really a drag on high speed computing I think. I use C a lot, probably too much, but I don't do much in the way of huge programs. Most are 12,000 lines or less and I only get about 3 months to deliver them at most. Also the systems and people I deliver to, don't have extensive OOP experience and since they often maintain, or extend/maintain/modify the code, C++ would be a hardship on some of that, where as C's basic structure is a bit more challenging, but gives more direct control for their work. The largest code I ever personally developed was just over 40,000 lines. </offthread> Regards, Les H -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
