Yes you can write completely safe, bullet-proof code in C++ and without sacrificing efficiency (and some times even improving it!) by using the high level C++ constructs. Examples are: find family (which includes find_if etc), search family, generate, fill, for_each, count, mismatch, equal, transform, copy, swap, replace, remove, unique, rotate, sort, bound, merge, partition, includes, set (like set_union), heap (like make_heap - makes sequences behave as heaps), comparisons (like min, max, lexicographical_compare), permutation, etc families. We can say it is an entirely completely safe, high level language of its own, and in this way you may never use loops for most things! -- Ioannis Vranos http://www23.brinkster.com/noicys
