c++ - How can I initialise a member array of objects that don't have a default constuctor?

Question

I was wondering if anyone could tell me how I'm supposed to initialise a member array of objects, in the occasion that the object does not have a default constructor (i.e. requires parameters).

For example:

class Foo
{
public:
   Foo() : 
      memberArray{bar(1), bar(3), bar(2)}   // **The compiler doesnt like this** 
   {}
private:
   Bar memberArray[3];
};


struct Bar
{
   Bar(std::int32_t param1) {  }
}

I'm using GCC 4.6.1, and compiling for c++11. Can anyone point out where I'm going wrong? (BTW. please don't suggest dynamically allocated memory, as I don't have it..)

You've got several problems: inconsistent case, use before declaration, missing semicolons, missing includes. This is a lot closer:

struct Bar
{
   Bar(int param1) {  }
};

class Foo
{
public:
   Foo() : 
      memberArray{Bar(1), Bar(3), Bar(2)}
   {}
private:
   Bar memberArray[3];
};
