Query on decorator pattern

Question

Hi

Refer below code:

I know I have implemented inheritance for one class nd other as decorator method..

I am getting confused with this. How decorator allows loose coupling compared to inheritance? In decorator method also, we have class pointer as data member of class.

Also in main function, what is makes a big difference to the new object creation of decorator class compared to passing a plain juice object to other decorator class?

Any reason of choosing decorator ?
