I have:
1) NetBeans 7.3 2) Qt by Digia v4.8.4. 3) MinGW compiler.
Could you help me initialize my array? I have failed, unfortunately. I understand that I have to use initializer_list. But what to include into my files and how to organize everything is a mystery to me.
Will you be so kind as to help me?
Figure.h
#include <initializer_list>
class Figure: public QObject{
Q_OBJECT
private:
int shape[4][4][4];
Figure.cpp
Figure:: Figure(){
std::initializer_list<int> init;
auto init = std::initializer_list<int>
(
{
{0, 0, 0, 0},
{0, 1, 1, 0},
{0, 0, 1, 0},
{0, 0, 0, 0}
,
{0, 0, 0, 0},
{0, 0, 1, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}
,
{0, 0, 0, 0},
{0, 1, 0, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}
,
{0, 0, 0, 0},
{0, 1, 1, 0},
{0, 1, 0, 0},
{0, 0, 0, 0}
}
);
...
private:
int shape[4][4][4] {
{{0, 0, 0, 0},
{0, 1, 1, 0},
{0, 0, 1, 0},
{0, 0, 0, 0}}
,
{{0, 0, 0, 0},
{0, 0, 1, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}}
,
{{0, 0, 0, 0},
{0, 1, 0, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}}
,
{{0, 0, 0, 0},
{0, 1, 1, 0},
{0, 1, 0, 0},
{0, 0, 0, 0}}
};

In your particular case, you don't even need to use initalizer_list
explicitly because static array can be initialized in the place of definition, and this is done via the syntax in the example above (requires C++11 compliance).
Initialization of shape
in constructor initialization list is possible too:
...
Figure::Figure(): shape {
{{0, 0, 0, 0},
{0, 1, 1, 0},
{0, 0, 1, 0},
{0, 0, 0, 0}}
,
{{0, 0, 0, 0},
{0, 0, 1, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}}
,
{{0, 0, 0, 0},
{0, 1, 0, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}}
,
{{0, 0, 0, 0},
{0, 1, 1, 0},
{0, 1, 0, 0},
{0, 0, 0, 0}}
} {
...
}
...
NOTE: Pay attention to the fact that you've missed additional parentheses in your try.
