this question has answer here: why these constructs (using ++) undefined behavior? 12 answers i felt such expression should invalid able compile , got answer 5. @ end felt if answer should 4 not 5. int main(void) { int i=1; // how next line evaluated ie in sequence?? i=2+2*i++; printf("%d",i); return 0; } the output got 5. can not understand how should give value. this undefined behaviour, since i modified more once between sequence points. instance, this compiler gives 4 answer, because puts increment after assignment. reasonable answer 6, if increment before assignment. but, you've found, compiler permitted make answer whatever wants, including 5. see here more sequence points , undefined behaviour.

i have 2 sheets different values. need find value 1 cell.sheet1 in sheet2 , copy value nextcell_in_the_same_row.sheet1 nextcell_in_the_same_row.sheet2. difficult explain let @ example bellow. e.g. before first sheet: b 1 aaa 123 2 bbb 456 3 ccc 789 4 ddd 122 second sheet: b 1 aaa 2 ada 3 cca 4 ccc after first sheet: b 1 aaa 123 2 bbb 456 3 ccc 789 4 ddd 122 second sheet: b 1 aaa *need find value in first sheet , copy value b2 because aaa in a1* 2 ada *value not exist in first sheet copy nothing* 3 cca *not need copy because no value in first sheet* 4 ccc *need copy value b3* thank much! use vlookup along iferror . =iferror(vlookup(a1, sheet1!a:b, 2, 0), "") this described (well described, way!) in question. drag formula down in sheet2 till bottom. vlookup takes value of a1 in sheet 2 (no sheet reference because value in same sheet formula) , looks in column of sheet1 . it returns second value (hence why 2 ) of table...

suppose have these 2 functions: finner<-function() { # complicated stuff, and... i<<-i+1 } fouter<-function() { i<-0 finner() print(i) } calling fouter() produces error: error in finner() : object 'i' not found . know, 1 way of fixing re-write example into fouter<-function() { finner<-function() { i<<-i+1 } i<-0 finner() print(i) } but if don't want nest functions way? in case finner heavy , complicated function (which might want move library), , fouter ad-hoc created function defines 1 iterator. have many fouter -class functions in code, nesting them require duplicating finner inside every single little 1 iterator definition. i suspect solution has environments, don't know how it. can help? you need access environment associated fouter function--where call finner is. can parent.frame , , can , set variables get , assign : finner<-function() { assign(...

i have function (based on parameters) move/rename image files mapped card reader drive in windows server drive after file renamed using template , appending incrementing number loop. there 3 cards of photos sent destination folder. each card being processed 1 after other because of file sizes , traveling on network can take quite time. is there way have function receive list of mapped card drives (not more 3) , run rename function simultaneously each card. my poor attempt illustrate trying follows: def collectcards(cards): card in cards: #my goal run each instance of following function asynchronously drv =renameimages(card) def renameimages(carddrive): #perform renaming functions return count_of_renamed_images you try using multiprocessing processes ( pool ) or threads ( pool.threadpool ). in both cases, difference in import - api stays same: from multiprocessing import pool my_pool = pool(3) # `cards` list of cards. send rename r...

#include<stdio.h> int main() { int buff[] = {1,2,3,4,5,6,9,10}; char c = (buff+1)[5]; printf("%d\n",c);//output 9 return 0; } can explain how happening , why recall: in c square braces [ ] implicitly *( ... ) . what going on in snippet of code provided not obvious pointer arithmetic. line: char c = (buff+1)[5]; ... equivalent following (by c standard): char c = *( ( buff + 1 ) + 5 ); ... points 7th element in array (6th position) , dereferences it. should output 9, not 19. remark: following note square braces, it's important see following equivalent. arr[ n ] <=> n[ arr ] ... arr array , n numerical value. more complicated example: ' '[ "]; < 0; i++; while ( 1 ); awesome (y)." ]; ... of entirely valid pointer arithmetic.

when in terminal, greeted prompt saying: computer_name:~ directory user$ (command input) then if use command "bash" , prompt changes to: bash-3.2$ (command input) now understand when use command "python" , taken python interpreter, seems pretty same commands usual work when switch bash. explain (if anything) happening here? when type bash taken new bash instance. if press ctrl + d exit. osx uses bash default shell.

i have need host couple soap12 messages in current ss webapi. have set of namespaces according rules , works expected, extent. can use multiple tools send soap service(s) , work. have added them service reference in visual studio project work; @ least until add authfeature. add authfeature or other native ss service, can no longer add service reference. my investigation has lead me namespace difference between datacontract(s) in servicestack.serviceinterface.auth namespace used in authservice. don't want limited authservice though, same applicable when swaggerfeature added , resources service set up. it imperative these 2 messages available in soap , client must have ability add them service reference consume them. my question: there way set datacontract namespace(s) native ss services keep namespace consistent our datacontract namespace? understand "could" compile , maintain own version of ss have ability change contractnamespace attributes of causing issues ca...

i have large dataset 5m rows. 1 of fields in dataset 'article_title', i'd search in real-time autocomplete feature i'm building on site. i've been experimenting mysql , mongodb potential db solutions. both perform when index used, example 'something%', need match titles within string, in '%something%'. both mysql , mongodb took 0.01 seconds index using forward-looking search, , 6 seconds full string search. i realize entire db needs scanned string-in-string type search common approach problem? solr , sphinx seem overkill 1 problem i'm trying avoid using them if possible. if got box 2 gb of ram , 40gb ssd (which can afford @ moment), able sub-second response time? in advance. -- update: tried fulltext index , while results fast, doesn't satisfy string-in-string search ("presiden" doesn't match "president"). i'm looking ways match string-in-string 5m row dataset. in case of mysql, can creat...
