How to initialize an array in C++ objects

Question

After reading How to initialize an array in C, in particular: Don't overlook the obvious solution, though: int myArray[10] = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 }; I tried something like this: ``` #include class Something { private: int myArray[10]; public: Something() { myArray[10] = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 }; } int ShowThingy(int what) { return myArray[what]; } ~Something() {} }; int main () { Something Thing; std::cerr << Thing.ShowThingy(3); } ``` And I get: ``` ..\src\Something.cpp: In constructor 'Something::Something()': ..\src\Something.cpp:10:48: error: cannot convert '' to 'int' in assignment ``` The obvious in this case is not so obvious. I really would like the initiation of my array to be more dynamic as well. I tired: ``` private: int * myArray; public: Something() { myArray = new int [10]; myArray = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 }; } ``` This looked funky to me to, and so to the compiler: ``` ..\src\Something.cpp: In constr…

Accepted Answer

You need to initialize the array in the constructor initialization list

```
#include <iostream>

class Something {
private:

int myArray[10];

public:

Something()
: myArray { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 }
{
}

int ShowThingy(int what) {
    return myArray[what];
}

~Something() {}
};

int main () {
   Something Thing;
    std::cerr << Thing.ShowThingy(3);
}
```

..\src\Something.cpp:6:51: sorry, unimplemented: non-static data member initializers

C++11 also adds supports for inline initialization of non-static member variables, but as the above error message states, your compiler has not implemented this yet.
