Problems with dynamic memory allocation in class

I am trying to create a class for a pizza restaurant where i have both a separate class for the Pizza and another for the restaurant. The restaurant class has a dynamic array of type Pizza whose size increases everytime another pizza is added to the restaurant.

Whenever i execute the program it stops working in the for loop before a new object is created and the addPizza function is called without giving an error or absolutely anything. I am still new to programming so i think i may be allocating the memory incorrectly thus causing it to freeze. Can anyone please help me on as to what i am doing wrong ?

Thank you.
