c++ - When a boost::shared_ptr might not be freed? -

-
afer reading topic c++ interview preparation (matt's answer) i've got question boost::shared_ptr. possible shared_ptr leak memory? how? shared_ptr uses reference counts, , means circular references can cause leaks. concretely: struct { shared_ptr<a> other; }; shared_ptr<a> foo() { shared_ptr<a> one(new a); shared_ptr<a> two(new a); one->other = two; two->other = one; return one; } the data structure returned foo never deallocated without manual intervention (set either of other pointers null). now fact every programmer should know; more interesting interview conversation it. options include: redesigning data structure pointer cycles not necessary; demoting @ least 1 pointer in every cycle non-owning reference (a bare pointer or weak_ptr ); a dedicated cycle collector ; as last resort, manually nulling out pointers @ appropriate points (this breaks exception safety).

jquery .live('click') vs .click() -

-
i wondering whether there circumstances better use .click(function {...}); rather .live('click', function {...}); ? from gather live option seems better option , hence using in circumstances instead of plain .click(), given lot of code loaded asynchronously. edit: part question. if i'm asynchoronously loading javascript in, .click still pickup elements in dom. right? there might times when explicitly want assign click handler objects exist, , handle new objects differently. more commonly, live doesn't work. doesn't work chained jquery statements such as: $(this).children().live('click',dosomething); it needs selector work because of way events bubble dom tree. edit: upvoted this, people still looking @ it. should point out live , bind both deprecated . can perform both .on() , imo clearer syntax. replace bind : $(selector).on('click', function () { ... }); and replace live : $(document).on('click', selecto

c# - Event parameter; "sender as Object", or "sender as T"? -

-
when write public events business objects, i've adapted habit of passing instance " sender object ", in addition additional specific parameters. asked myself why not specifying class ? so more experience; do ever pass distinct class sender in event ? , if so, decision criteria when ok/not ok? don't extreme. eventhandler(object sender, eventargs e) has object sender can use in many circumstances. doesn't mean strongly-typed sender evil. strongly-typed sender useful when delegate not going used(like eventhandler ) e.g. public delegate void savehandler(controller sender, eventargs e); now other developers(or using library) can recogonize sender have to controller , , glad not code this: public void mysavehandler(object sender, eventargs arg) { var controller = sender controller; if (controller != null) { //do } else { //throw exception @ runtime? //it can avoided if sender strongly-typed } } and can

c++ - Array Initialization Macro -

-
i trying come macro following, my_macro(type,name,args...) my_macro(int,_array,1,2,3) and expand to, int _array[] = {1,2,3}; coll* __array = my_call(&array[0],&array[1],&array[2]); is possible with/without compiler specific magic? my_call expects variable number of arguments , not want pass array directly. edit: using accepted answer following question var args, macro returning number of arguments given in c? so can find how many elements in array. you can start (c99, not gcc-specific): #define my_macro(type, name, ...) \ type name[] = {__va_args__}; the my_call part more difficult; there macros online can count number of arguments, need boost.preprocessor (which should work in c) apply my_call consecutive elements of array. how many elements have maximum? might want like: #define count(...) count2(__va_args__, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0) #define count2(a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, cou

c++ - const char * const versus const char *? -

-
i'm running through example programs refamiliarize myself c++ , have run following question. first, here example code: void print_string(const char * the_string) { cout << the_string << endl; } int main () { print_string("what's up?"); } in above code, parameter print_string have instead been const char * const the_string . more correct this? i understand difference 1 pointer constant character, while 1 constant pointer constant character. why both of these work? when relevant? the latter prevents modifying the_string inside print_string . appropriate here, perhaps verbosity put off developer. char* the_string : can change char the_string points, , can modify char @ points. const char* the_string : can change char the_string points, cannot modify char @ points. char* const the_string : cannot change char the_string points, can modify char @ points. const char* const the_string : cannot change char the

algorithm - Maximum Coin Partition -

since standing @ point of sale in supermarket yesterday, once more trying heuristically find optimal partition of coins while trying ignore impatient , nervous queue behind me, i've been pondering underlying algorithmic problem: given coin system values v 1 ,...,v n , limited stock of coins a 1 ,...,a n , sum s need pay. we're looking algorithm calculate partition x 1 ,...,x n (with 0<=x i <=a i ) x 1 *v 1 +x 2 *v 2 +...+x n *v n >= s such sum x 1 +...+x n - r(r) maximized, r change, i.e. r = x 1 *v 1 +x 2 *v 2 +...+x n *v n - s , r(r) number of coins returned cashier. assume cashier has unlimited amount of coins , gives minimal number of coins (by example using greedy-algorithm explained in schoening et al.). need make sure there's no money changing, best solution not give of money (because solution optimal in case). thanks creative input! if understand correctly, variant of subset sum . if assume have 1 of each coin ( a[i] = 1 each i ), sol

declaration - Why doesn't C# let you declare multiple variables using var? -

-
given following: // not problem int = 2, j = 3; so surprises me this: // compiler error: implicitly-typed local variables cannot have multiple declarators var = 2, j = 3; doesn't compile. maybe there don't understand (which why i'm asking this)? but why wouldn't compiler realize meant: var = 2; var j = 3; which compile. it's point of possible confusion programmer , compiler. for example fine: double = 2, j = 3.4; but mean? var = 2, j = 3.4; with syntactic sugar kind of thing headache no 1 needs--so doubt case ever supported. involves of compiler trying little bit clever.
