Address of Operator Suffix

[DaveRUK]

Hi

I am new to C++ and am having a problem. I am currently working on references and pointers and I keep coming accross lines like this

SimpleCat::SimpleCat(SimpleCat&)
{
	cout << "nCopy constructor calledn";
}

My question is. What does it mean when the & operator is placed after the identifier?

Thank you

David

If you place a word/character after SimpleCat&, it means that that word/character is a reference to SimpleCat. For example:

SimpleCat::SimpleCat(SimpleCat&x)

This means that x is a reference to SimpleCat.

SomeType& is a reference to SomeType
&Variable is the address of Variable.
