Initializing Non-default-constructible Elements in a Member Array

[better_cs_now]

Hello all,

In this code:

class Bar {
public:
Bar(int) {} // ***Not default constructible***
};

class Foo {
public:
Foo() : m_Bar({Bar(1), Bar(2)}) {} // Not syntactically correct!
private:
Bar m_Bar[2];
};

What is the proper way to initialize m_Bar? Thanks to all!

Best,
Dave

There is no way, proper or otherwise. Use a a standard container
(vector) which can be copy-initialised from a static Bar array.
