How does new know how much memory to allocate??
Hi,
I was just wondering how the new operator (in C++) knows how much memory to allocate when creating an object of a class such as shown below:
i.e
class Books
{
...

Books textbook = new Books();

}

[CODE=C#]
protected void button_add(obje ct sender, EventArgs e)... -
Typecast operator
I'm new to C# and come from an embedded C background so I hope I'm not embarassing myself not too much.
