c++ - array initialization unknowledge -

-

i know basic way initialize arrays.i error on compiler int array initialize on constructor not understand it.i need help. code is:

cpp file:

#include <iostream> using namespace std; #include "validationcontroller.h"  validationcontroller::validationcontroller() {     // todo auto-generated constructor stub     monthtable[12]={0,3,3,6,1,4,6,2,5,0,3,5}; }  validationcontroller::~validationcontroller() {     // todo auto-generated destructor stub }

and header file:

#ifndef validationcontroller_h_ #define validationcontroller_h_  class validationcontroller { public:     int monthtable[];//={0,3,3,6,1,4,6,2,5,0,3,5};     validationcontroller();     virtual ~validationcontroller(); };  #endif /* validationcontroller_h_ */

the error is:

..\src\validationcontroller.cpp:13: warning: extended initializer lists available -std=c++11 or -std=gnu++11 [enabled default]

and

..\src\validationcontroller.cpp:13: error: cannot convert '' 'int' in assignment

i not want make static. there solution keeps declaration header file?or should declare , initialize in .cpp file @ once after imports.

if can use c++11 write: in header file: #include 

class validationcontroller { public:     std::array<int, 12> monthtable;     validationcontroller();     virtual ~validationcontroller(); };

in source file:

validationcontroller::validationcontroller()  : monthtable{0,3,3,6,1,4,6,2,5,0,3,5} {}

or if not need change contents:

in header file:

#include <array>  class validationcontroller { public:     const static std::array<int, 12> monthtable;     validationcontroller();     virtual ~validationcontroller(); };

in source file:

const std::array<int, 12> validationcontroller::monthtable = {0,3,3,6,1,4,6,2,5,0,3,5};

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
