memory allocation exception ??

Question

Hi

Define the exception class MemoryAllocationException and then revise the definition of the method push in the class LinkedStack so that it throws this exception if it cannot allocate a new node.

Ty in advance

Well defining the MemoryAllocationException class could be as simple as this: public class MemoryAllocationException : Exception { public MemoryAllocationException(string message) : base(message) { } } I don't know anything about the LinkedStack class which I assume you created in a previous project but it sounds like it is a limited to a maximum number of nodes (say maxNodes). If you keep a count of the nodes as new ones are added (or existing ones are removed) in a variable countNodes say then you'll need to insert something like this at the beginning of the push method: if (countNodes == maxNodes) { throw new MemoryAllocationException(Maximum number of nodes for LinkedStack has been reached); }
