I want to initialize a structure of static strings. The strings are not to be changed. I'm not quite sure if I should specify each string to be const or just the struct. And how do I get the strings in to the struct?
ClassA.h

#pragma once
#include <string>

typedef struct _myScreen
{
  std::wstring line1;
  std::wstring line2;
  std::wstring line3;
} MyScreen;

class ClassA
{
public:
  ClassA(void);
  void Test(void);
private:
  static const MyScreen ls1;
};

Open in new window

ClassA.cpp

#include "StdAfx.h"
#include "ClassA.h"

ClassA::ClassA(void)
{
  ls1 = {L"Hello", L"Goodbye", L"Friday"};
}
void ClassA::Test(void)
{
  std::wstring s = ls1.line1;
}

Since the member 'ls1' is static, there is absolutely no need to do that dynamically as in the above - just make it

#pragma once
#include <string>

typedef struct _myScreen
{
  std::wstring line1;
  std::wstring line2;
  std::wstring line3;
} MyScreen;

class ClassA
{
public:
  ClassA(void);
  void Test(void);
private:
  static const MyScreen ls1;
};

Open in new window

and

#include "StdAfx.h"
#include "ClassA.h"

ClassA::ClassA(void)
{
}

_MyScreen ClassA::ls1 = {std::wstring(L"Hello"), std::wstring(L"Goodbye"), std::wstring(L"Friday")}; // initalize the static struct

void ClassA::Test(void)
{
  std::wstring s = ls1.line1;
}
