ok lets go thru your code....

your exception classes will need default constructors or arguments passed to them.

destructor doesnt need if(s). just the delete[]s will do nicely.

throw Stack_Full_Exception();
should be
throw Stack_Full_Exception;
or
throw Stack_Full_Exception(args);
depending on available constructors. see point 1.


You cant nest other functions inside main!!!!
Thats illegal.
Your funcs to check if a palindrome is never called from main.
Fix those and repost if that dont do it.
