creating multiple instances of a class dynamically

[manontheedge]

I'm trying to create multiple instances of a class dynamically. For example ...

Class A
{
...
...
};

Class B
{
    B( int value )
    {
        for( int i = 0; i < value; i++ )
        {
            // I THINK THIS IS RIGHT
            m_a[i] = new A();
        }
    }
    ...
    ...
private:
    // I BELIEVE THIS IS WHERE I'M GOING WRONG
    A** m_a;
...
...
};

... I realise what I'm doing is wrong, but I can not remember how to do this. It's been a while since I've had to use c++, and I just can't figure this out. Any help is appreciated.

Why don't you just use a vector of A in B. In B's constructor you can simple set the vector to the right size.
