Object initialization

[Bob Altman]

This question deals with unmanaged C++ (Visual Studio 2005).

Suppose I have a class named MyClass with a constructor that takes an
argument. How do I create an instance of type MyClass as a member variable
(see below)?

Class Test
{
public:
Test(void); // Constructor
~Test(void); // Destructor

private:
MyClass m_myClass("My argument"); // error C2059; syntax error :
'constant'
};

TIA - Bob

Bob,

I think you'd do it like this:


Test() : m_myClass( "Hello" )
{
}

private:
MyClass m_myClass;
