A good compiler will optimize it that well. Your code is wrong. The vector x is of size zero. It should crash. You need: vector<int> x; x.reserve(5); x[0] = 5; or: vector<int> x(5); x[0] = 5; _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
