this question has answer here: is short-circuiting logical operators mandated? , evaluation order? 7 answers i'm getting difficult understand how following programs work, kindly me in understanding. int x=2,y=0; (i) if(x++ && y++) cout<<x<<y; output: (ii) if(y++ || x++) cout<<x<<" "<<y; output: 3 1 (iii) if(x++||y++) cout<<x<<" "<<y; output: 3 0 kindly explain me how program working , also, makes difference between (ii) , (iii). you looking @ "c++ puzzle" using 2 languages tricks. the first postincrement uses value of variable first, increments variable. so x++ has value 2 in expression , x becomes 3 y++ has value 0 in expression, , y becomes 1 && , || or both operators short-circuiting. look @ && first. in order , tru...

i have 3 functions in javascript: function a(){ b(data); } function b(data){ element.on('click',function(){ c(data); }); } function c(data){ //process data } function c data processing, data needs passed on click event, have defined in b. so, need pass data b too, ensure c gets it. here, main program , i'd rather not define click event there. there other way pass data directly c a? is there other way pass data directly c a? you need pass call of c th data b that: function a(){ b(function(){ c(data); }); } function b(data){ element.on('click', callback); } function c(data){ //process data } it work same way code have, has decoupled b c.

how can determine given m x n matrix desribing two-mode network whether connected or not? of course once can create data structure finding out – there mathematical solution? i found out n x n matrices (one-mode network) easy: solution be: m * m , looking @ diagonal in resulting matrix. if there 0 on diagonal not connected. isn't true? what suggestion both problems? it not simple one-mode networks , you're close. the network matrix m tells node connected other node in 1 step. m * m tells node connected other node in exactly two steps, m ^ 3 whether in exactly three steps, , on. "exactly" important, because if nodes not connected (zero diagonal elements), m * m not obtain two-step connectivity, loses one-step connectivity. the products (powers) therefore more useful if nodes connected themselves: a = (m + eye(size(m)) > 0) this step converts weighted matrix pure adjacency matrix. now (a ^ > 0) gives information whether 2 nodes...

i have view image , viewmodel have commands handle button (1,2,3,4) clicks. in work area allow user give inputs. depending upon input users allowed click button; each button leads 1 new window(view viewmodel; model taken inputs). new window have own logic showing data depending upon model injected viewmodel. as per mvvm standards, specify respective view , viewmodels each button? (in view / view model). how can specify same? basically viewmodel link between view , model, each combination of view , model should have separate viewmodel (if valid). in experience in cases dealing 2 kinds of views: small views such icons, advanced buttons , on (which more isolated , more have no reference parents easy manage , generalized) large views such windows, panels (which have lot of children , more changed later) for small views common viewmodels can used multiple views. large views (considering possible changes in future) it's better not use single shared viewmodel...

i using following code windowing data , finding mean of each window. used starting each new window directly @ end of previous window. how code modified each new window starts @ 50% overlap prior window. fq = 51.2; //sample rate of accelerometer windowlength = 5; //length each window in seconds startpos = 1; //starting position 1st win endpos = startpos + (windowlength * floor(fq)); //end position 1st win totalwindows = floor(length(walk)/fq/windowlength); stats = zeros(windowlength,9); = 1:totalwindows epmean = mean(walk(startpos:endpos,:)); //calculate window mean //x, y & z axis values each stat walkfeature(i,1:4) = epmean; //next window position startpos = endpos+1; endpos = startpos + (windowlength * floor(fq)) end not optimized that's close original code , allow specify desired overlap : windowlengthinpoint = windowlength * floor(fq) ; %// store value overlap = 0.2 ; %// in portion of windowlength - 20% in exa...

yesterday had memory corruption going on , i'm highly suspect of how record arrays being allocated , deallocated. short version demostration: type tmyrecord = record w: word; s: string; end; tmyrecordarray = array [1 .. 315] of tmyrecord; tarraypointer = ^tmyrecordarray; var pagebase: tarraypointer; procedure ttestform.formcreate(sender: tobject); var irecord: tmyrecord; begin pagebase := allocmem(sizeof(tmyrecordarray)); irecord.w := 1; irecord.s := 'test'; pagebase^[1] := irecord; end; procedure ttestform.formdestroy(sender: tobject); begin pagebase^[1] := default (tmyrecord); freemem(tpagebase); end; i'm sure i'm not doing right, suggestions appreciated. the first thing code present works. finalizes , deallocate correctly without leaking. i'll try answer question more generally. strings managed types , compiler needs use special memory allocation routines able manage them: new , dispose . allocate with ...

i wondering if knew why ib has inexplicable high lighted areas on odd nib here , there.. below example: what mean light area within area marked out in red... there's no views below split view, there's no bounds correspond , far there's nothing complaining "misplaced views" etc... it? update: worked out when last happened that weird "area" same size rightmost nsview (whether embedded in nssplitview or 2 nsviews side side. many thanks adrian s it's due bug in xcode interface builder. , in experiments it's been predictable according following explanation: the lighter colored area intended highlight container view of current selection. have nstextfield within nsbox, , select text field, box highlighted. it's purpose dim out outside scope can make constraints in. you can see it's dimming down of outside box, if nothing selected, whole ib view port displayed in lighter shade. the bug when make selection, ib cl...

this conceptual, non language specific question. i know these less ideal, think question still quite clear , simple... what want just; write class array of n dimensions/axes, each of length m , , index them. write generalised function can iterate through elements in such array via n nested for loops, array of dimension n . have function nothing, "template", can interact function performs specific action, eg function sets every value in array 1. i don't have deep enough programming knowledge know how easy such thing implement, in language. while idea extremely simple, haven't seen similar example of such flexible , inert "meta" function, or if such thing practicable. so if give me feedback towards performing such implementation, speaking generally, or citing specific language example, helpful. edit: pseudocode illustration class array(arrayaxesnumber, arrayaxeslength) trackallelements (array) #iterate through arrayaxes1# ...
