c++ - Clarification on postfix/prefix operators on iterators -

in accelerated c++ andrew koenig writes following code introduction templates , generic functions. code skip first element in container? or copy first iterator object before incrementing: template<class in, class out> out copy(in begin, in end, out dest) { while (begin != end) *dest++ = *begin++; return dest; } in other words, behave code?: template<class in, class out> out copy(in begin, in end, out dest) { while (begin != end) *dest = *begin; dest++; begin++; return dest; } post incrementing iterator (or else matter) may confusing doing pretty straight forward. makes copy of value, increments original , returns copy. location being referred "*dest++" same "*dest", difference after statement finishes dest refer next iteration in iteratable. the problems arise when programmers use incremented variable repeatedly in same expression. (which used brain teaser , resulting effect varies language language)

ios - How do I (the designer) test and use an iPhone in development if I don't have access to computer in which the code is being written? -

hi i'm intending have iphone app developed coder us. live in uk. when app being developed, there way can preview , use app being developed, see if designs , functionality correct? basically app equivalent of seeing developer url of website being developed. -thanks you need give developer udid of device. you can find via itunes. the developer add udid developer profile. can create install files (the file extension .ipa ) device can use. sends ipa file , use itunes install it. another approach use testflight . can register device site , developer's account on site. developer can udid web site , upload .ipa file site. once he's done that, can install app directly web site without downloading mac or pc first. note still reasonably secure because app encrypted , can run on devices included in developer's profile.
