Can someone help me with a beginner's question?
 
Say I have the following declarations:
 
Class A: {
   int a;
   int b;
}
 
Class B: public A {
...
}
 
And constructors:
 
Class A::A(int x, int y)
{
...
}
 
Class B::B(int z, int x, int y)
       :A(x, y)
{
...
}
 
If I declare B b1(1,1,1), b2(2,2,2), no problem.
 
But if I want to declare a table (array) of Bs, say , 2, how do I do it?
 
I tried the following:
 
B b[] = { {1, 1, 1}, {2, 2, 2}};  // won't work
B b[2];                 // won't work obviously

The only way I could make the array method to work was to declare (void)
in
the constructors, and create some member functions say, create(int, int,
int)
within A and B. It looks pretty ugly. 
 

Any toughts or hints?

Thx very much for your time in advance,
 
Brian Chan.
