Initializing a static const array of const strings in C++
For C++11, you can make the initialisation inside your class declaration, in your .h file. However, you will need to include constexpr in your .cpp file too. Example for the case above:
In your week.h file, write:
class Week {
public:
static const constexpr char* const days[] =
{ "mon", "tue", "wed", "thur","fri", "sat", "sun" };
};
In your week.cpp file, write somewhere:
constexpr const char* const Week::days[];
Make sure you enable C++11, e.g. compile with
g++ -std=c++11 week.cpp
First of all, you need an array, not a pointer.
static const char * const days[] = {"mon", "tue", "wed", "thur",
"fri", "sat", "sun"};
Second of all, you can't initialize that directly inside the class definition. Inside the class definition, leave only this:
static const char * const days[]; //declaration
Then, in the .cpp file, write the definition
const char * const Week::days[] = {"mon", "tue", "wed", "thur",
"fri", "sat", "sun"};
Update for C++11 Now you can initialize members directly in the class definition:
const char * const days[] = {"mon", "tue", "wed", "thur",
"fri", "sat", "sun"};
