c++ - Std::vector to const std::vector* -



c++ - Std::vector<struct> to const std::vector<const struct>* -

i have private variable std::vector<some struct> can somehow pass vector function homecoming value, no "write" access, not able add together new elements it, , won't able modify elements(e.g. const std::vector<some const struct>*. how can that? thought have create new vector constant pointers existing elements. there improve solution?

you can't modify elements of vector via pointer or reference const vector. next safe:

const std::vector<some_type>* get_pstuff() const { homecoming &the_vector; } const std::vector<some_type>& get_rstuff() const { homecoming the_vector; }

on other hand, might more idiomatic homecoming const_iterators begin , end of vector:

std::vector<some_type>::const_iterator cbegin() const { homecoming the_vector.cbegin(); } std::vector<some_type>::const_iterator cend() const { homecoming the_vector.cend(); }

c++ vector

Php operator `break` doesn't stop while -

Php operator `break` doesn't stop while - have weird issue, break doesn't break while loop , maintain rotating. logically should break cycle , set output while ($c++ != 5) { // here curl request, doesn't relevant have removed preg_match("!<.*?>(\s*)[^<>]*?{$to}<!", $resp, $result) ; // echo 'cnt = ' .count($result).'<br>'; if(!count($result)) { $amount = 0; echo 'sleep called'; sleep(4); exit; continue; } else { $amount = trim(@$result[1]); $amount = round($amount + $amount * $exchange_ratio, $precision); echo 'break happen<br>'; break; } } so output cnt = 2 break happen cnt = 0 sleep called so skipped break , maintain rotating. how so? edit works fine on localhost issue php version? ...
