quote the c++ standard library: tutorial , handbook : the portable way of using templates @ moment implement them in header files using inline functions. why this? (clarification: header files not only portable solution. convenient portable solution.) it not necessary put implementation in header file, see alternative solution @ end of answer. anyway, reason code failing that, when instantiating template, compiler creates new class given template argument. example: template<typename t> struct foo { t bar; void dosomething(t param) {/* stuff using t */} }; // somewhere in .cpp foo<int> f; when reading line, compiler create new class (let's call fooint ), equivalent following: struct fooint { int bar; void dosomething(int param) {/* stuff using int */} } consequently, compiler needs have access implementation of methods, instantiate them template argument (in case int ). if these implementations not in header, wouldn

i have custom tableviewcell imageview inside it. layout such: i want use autolayout calculate height of cell in method cgsize size = [cell.contentview systemlayoutsizefittingsize:uilayoutfittingcompressedsize]; so set constraints this basically these constraints pin each element edge of superview or view above/below. the problem there 1 more constraint want add imageview's aspect ratio. want set imageview's height half of width. if directly set aspect ratio constraint 2:1 unable simultaneously satisfy constraints error. tried change priority high , still no luck. can achieve using autolayout? the reason why constraints work , automatic height correctly calculated ui elements have own intrinsic size (the size make fit content). therefore, imageview has size fit image put inside. can't both use intrinsic size , specify own (even if want change 1 of dimensions). a solution see have static height constraint on uiimageview , plus aspect ration

this question has answer here: is possible change default value of primitive data type? 6 answers i'm curious know, possible change default value of e.g. int in c# , can have value -1 instead of 0. public class foo { public int i; } ... foo = new foo(); console.write(foo.i); so code must return -1 without explicit initializing public class foo { public int = -1; } can sure, don't print somewhere like #define true false but default value of int p.s. interest purposes only. no, basically. assuming don't initialize fields, memory space zeroed. shouldn't expose fields directly anyway . one trick have seen around (used capnp serializer, works against raw memory, not objects) use xor. example: if default -1, can xor value in , out: public class foo { private int i; public int { { return ^ -1; }

given string , non-negative int n, return larger string n copies of original string. string_times('hi', 2) → 'hihi' string_times('hi', 3) → 'hihihi' string_times('hi', 1) → 'hi' def string_times(string, times): return string*times any sequence in python (of string example) can replicated multiplying sequence integer. although careful around numpy arrays , perform multiplication on every item in array.
