according herb sutter's c++ coding standards: 101 rules, guidelines, , best practices programmer should avoid c-style casting: c-style casts have different (and dangerous) semantics depending on context, disguised behind single syntax. replacing c-style casts c++-style casts helps guard against unexpected errors i trying pass pointer p_ctrl winapi callback function, want use dword_ptr parameter of callback function (below example working, contains c-style casts commented): wndctrls* wndctrls::button ( wndctrls* const p_ctrl, hwnd hwnd, rect const &rc ) { p_ctrl->ctrl = createwindowex ( 0, l"button", p_ctrl->w_classnamebutton.c_str (), ws_visible | ws_child | bs_ownerdraw, rc.left, rc.top, rc.right, rc.bottom, hwnd, 0, (hinstance)getwindowlongptr ( hwnd, gwl_hinstance ), // problematic c-style cast know workaround p_ctrl ); setwindowsubclass...

i'm having trouble trying sum lists have. i'm having: [[[_g8511,0,1,_g8520],[_g8526,1,0,0],[_g8541,_g8544,0,1]], [[1,1,1,_g8568],[0,1,0,1],[0,_g8592,0,1]], [[1,0,_g8613,_g8616],[0,1,_g8628,0],[0,_g8640,_g8643,1]]] my problem try sum elements inside list. know how iterate through it, need either ignore intern variables, or make them 0. i tried using sum_list(list, sum), figured can not handle intern variables. question how can either ignore elements not having value of 0 or 1, or how can make internal variables 0? you use nonvar/1 predicate succeeds when argument not variable. you write sum_list predicate: sum_list(list,sum):-flatten(list,list2),sum_list2(list2,sum). sum_list2([],0). sum_list2([h|t],sum):- var(h),sum_list2(t,sum). sum_list2([h|t],sum):- nonvar(h), sum_list2(t,sum1),sum sum1+h. note in above solution since need sum , lists nested used flatten/2 predicate flatten nested list flat list. ?- sum_list([[[_g8511,0,1,_g8520],[_g8526,1,...

perhaps question obvious answer, i'm new c , have spent hours trying work myself , searching on site. i'm building simple program starts variable holds number (1234 in case), , 1 of options in program allows user change variable (value). so, user asked enter new number value hold. asked same numbers again. if numbers entered same, value should updated hold these new numbers (stored in both newvalue , newvaluecheck ). i'm trying figure out how update value assigning numbers stored in new variables no matter try, when menu loops around , ask program numbers in value , it's stuck 1234. again, sorry if obvious, it's driving me insane. int x = 1; int value = 1234; int enteredvalue = 0; int newvalue = 0; int newvaluecheck = 0; while (x != 0) { printf("1. example"); printf("2. change value"); scanf("%d", &atm); switch (x) { case 1: //code here break; case 2: printf(...

i trying print out elements of char array consists of both numbers , letters. code is: char *receiveinput(char *s) { scanf("%99s", s); return s; } int main() { char str[100], inp[50] = ""; printf("enter string"); receiveinput(str); char ctostr[3]; int num = 3; char c = (char)(num); ctostr[0] = c; ctostr[1] = str[0]; ctostr[2] = '\0'; strcat(inp, ctostr); printf("%s\n", inp); return 0; } lets str in "hey" , inp should contain , print "3h " instead prints 'h' when ctostr[0] = c (which char 3). how print elements contain both numbers , letters? number 3 not same character '3'. example in ascii table character '3' has integer code in hex 0x33 while in ebcdic table has code 0xf3 . you can write int num = 3; char c = num + '0'; ctostr[0] = c; provided num less 10.

i install bootstrap in angular2-meteor project with: meteor npm install --save bootstrap@4.0.0-alpha.5 then dropdown , collapse component dont work, when add bootstrap scripts lines in index.html body bootstrap component work fine. why if plan use bootstrap 4 css angular 2 suggest evaluating 1 of libraries provide native bootstrap widgets: https://ng-bootstrap.github.io those widgets written angular 2 , offer apis make sense in context of angular 2. since library written ground-up angular 2 won't need dependency on jquery nor bootstrap's javascript (it enough include bootstrap's css , mentioned library)

i'm having troubles difference calculation between 2 dates. my $todaydate = datetime->now; @updatedatefields = split /\//, $proteinobj->{lastupdate}; #yyyy/mm/dd $updatedatetime = datetime->new( year => @updatedatefields[0], month=> @updatedatefields[1], day=> @updatedatefields[2] ); $dayssincelastupdate = $todaydate - $updatedatetime; $dfd = datetime::format::duration->new(pattern => '%y years, %m months, %e days'); print "last update was: ". $dfd->format_duration($dayssincelastupdate). " ago.\n"; and output this: last update date: 2015/01/13 last update was: 0 years, 22 months, 0 days ago. it does't display 1 years, 10 months, 0 days ago. you need enable normalise option in datetime::format::duration object, this my $dfd = datetime::format::duration->new( pattern => '%y years, %m months, %e days', normalise => 1, );
