Re: Initialize an array of classes?

Hi Bob,
Currently you cannot use member initialization list for a nonstatic array of a class if it does not have a default constructor. When you try to initialize the array, you will encounter the compiler
error C2536. You may refer to:
Compiler Error C2536
http://msdn.microsoft.com/en-us/library/9f53ks1w.aspx
If the class has a default constructor, you can explicitly initialize it like the following code:
class CInner {
public:
// Constructor
CInner(int x) : Value(x) {}
CInner(){}
// Member variable
int Value;
};
class COuter {
public:
CInner InnerValue;
CInner m_Inners[2];
// Constructor
COuter() :
InnerValue(2),m_Inners()
{}
};
The code can be compiled, however you may encounter the warning C4351 and I do not think that it is useful to use such initialization for an array.
You can refer to this article for further inforamtion:
Compiler Warning (level 1) C4351
