c++ - byte representation of ASCII symbols in std::wstring with different locales -


windows c++ app. have string contain ascii symbols: std::wstring(l"abcdeabcde ... other ascii symbol"). note std::wstring uses wchar_t.

question - byte representation of string depends on localization settings, or else? can assume if receive such string (for example, windowsapi) while app running bytes same on pc?

in general, characters (not escape sequence) wchar_t , wstring have use same codes ascii (just extended 2 bytes). not sure codes less 32 , of course codes greater 128 can has different meaning (as in ascii) in moment of output, avoid problem on output set particular locale explicitly, e.g.:

  locale("en_us.utf-8")

for standard output

  wcout.imbue(locale("en_us.utf-8"));

update:

i found 1 more suggestion adding 

  std::ios_base::sync_with_stdio(false);

before setting localization imbue

see details on how can use std::imbue set locale std::wcout?

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...

c# - Randomly pick a specific int from a 2D Array -

i'm trying randomly specific integer (1) 2d array list filled 0's , not many 1's. made this, , works: while (wallslist[randomx, randomy] != 1) { randomx = randomizer.next(34); randomy = randomizer.next(34); } the downside of it, it's takes time find 1 time int (1), , have process on 1000 times since new 1's added , removed 2d array each time. takes 3m launch program know if there optimized version of this, searched lot , found solution 1d arrays. time. you have sparse array. why not represent list of x/y int pairs? then, if x/y int pair in list, it's 1, if not, it's 0. then, find random value/cell containing 1, pick random value list. you use list like new list <tuple<int, int>> { new tuple<int, int>(1, 5), new tuple<int, int>(2, 7) }
