can explain me why code works (why return value)? int main() { int *ptr = new int(113); int &rptr = *ptr; delete ptr; cout << rptr << endl; return 0; } basically, return value get: -572662307 what doing results in undefined behavior, fact you're getting number reasonable behavior. when perform sequence: int *ptr = new int(113); int &rptr = *ptr; the reference rptr refers integer created line new int(113) . on next line, execute delete ptr; this deletes int , meaning object no longer exists. pointers or references reference deallocated object, causes undefined behavior. consequently, when print rptr with cout << rptr << endl; anything can happen. here, you're getting garbage data, program have crashed or reported debug error message. interestingly: value printed (-572662307), treated 32-bit unsigned value, 0xdddddddd. bet memory allocator putting value deallocated memory debug memory errors one. hope helps!

i found regular expression in old system i'm working on. (\s*)* i'm pretty sure " * " @ end redundant want make sure not doing before remove it. it's causing performance issue when it's used in regex.matches() method point hangs entire system if string used parameter has 25+ spaces does knows if particular syntax has special functionality? ps: pretty huge system can't test every posible scenario assuming inner * greedy, then, yes, think outer 1 redundant. outer * attempts repeat sub-match, there ever 1 instance of sub-match because it's greedy.

is there way give user raw_input, give null response ( "" ) if nothing typed within x amount of time? i'd give user 10 seconds enter options when script starts, if time expires (or press enter), continue script. if know applescript, i'd display dialog "enter options" giving after 10 in python if in unix-land, can use python's signal library , use alarm . otherwise, think raw_input totally thread-blocking. see this answer implementation help.

i have been searching information regarding topic found no direct answer. possible following happen: pc 1: -opens udp socket in port x -sends request dns server resolve name meanwhile a hacker captures packet in internet, , himself answers request wrong answer can happen? if not, prevents this? dns uses ssl or security mechanism? our operative systems use secure communications dns servers? thanks in advance the scenario present possible. it's 1 of reasons why dnssec invented. dnssec allows resolver client check chain of cryptographic signatures dns record way tree trust anchor (which dns root).
