this question has answer here: why isn't sizeof struct equal sum of sizeof of each member? 11 answers padding in structures in c 5 answers with below code: struct s { unsigned char b1 : 3; int i; }; i can deduce char b1 of 1 byte , using 3 bits of , int 4 bytes when try print out size of s, 8 bytes instead of 5 bytes(1 char+4 int) expected , not understanding obvious. can explain why size of s 8 bytes?

for example, path 1 below: <path d="m 35 50 l 35 35 l 90 90 z" fill="goldenrod"/> if contour closed (z-command) , simple polygon, sum of interior angle s is sa = 180 * (n - 2) where n number of vertices. here 3 vertices, sa = 180 (it works concave polygons, not self-intesecting ones (they 'not simple'))

i can't understand 1 paragraph when read data structure , algorithm analysis in java. can tell me? in applications sure number of enqueues not larger capacity of queue, wraparound not necessary. stacks, dequeues performed unless calling routines queue not empty. error checks skipped operation, except in critical code. not justifiable, because time savings achieve minimal. thanks without seeing full context in paragraph sits, exact answer might difficult. appears saying dequeue operations performed when queue known not empty. therefore, error checks empty queue skipped operation, on basis saving time not performing check. however, time savings realized not doing empty check minimal, , risk of not checkout outweighs minimal performance gain. in more human readable terms, when working queues (as stacks), there potential need make sure queue not empty before trying dequeue (removal) operation. check ignored on grounds saves time , boosts performance. book readin

we rewriting our .net application. current application has 4 windows services. first service accepts requests ui , updates ui publishing events refreshing ui. service internally uses 2 thrall pools max 16 threads each service gui. requests ui requires business processing passed on worker process windows services(there 2 such windows service).msmq used passing requests , forth between services. fourth windows service acts load balancing , directs requests first service workers. services running on same box now while rewriting, know if should maintain same architecture or can clubbed same service separate threads. better performance perspective. for running on same box, think may require scale multiple boxes in future? the architecture involving multiple services more scalable, more maintainable , more flexible. of key benefits are, your architecture more loosely coupled you can scale each service / workload separately you can replace each service in different tech

[sold] => sold [to let] => let [let] => let any highly appreciated. in advance. here i've used in_array() match key given keys 'sold','to let','let' , unset key $input array , push key value array. <?php $input = array( 'for sale' => 'f
