C / C++ / MFC

Some compilers initialize memory to zero. But for compatibility reasons, the C++ standard leaves (built-in type) members untouched (I don't know the latest one).

   class Any
   {
     ....
     int var1 = 2; // This is an initializer.
     int var2;  // No initializer so set to default value (zero.)
     }
<pre>

This happens regardless of how construction occurs.

See my answer above. You have misunderstood the standard.

class A
{
  //..
public:
  A();
  A(int);
  A& operator=(int);
};

class B
{
  A m_a;
public:
  B() { m_a = 3; /*second call, after A::A()*/}
  // B() : m_a(3) /*first and last call of A::A(int)*/ {}
};

They sought it with thimbles, they sought it with care;
They pursued it with forks and hope;
They threatened its life with a railway-share;
They charmed it with smiles and soap.
