post all your updated code
you need to fix at least three things:
- the format string in printf()
- increment the pointer in getWidgets()
- set the .number member for all your elements

actually, precedence rules will execute that as *(s_ptr++) giving «expression result unused» warning
the unneeded dereference is a conceptual error, but the should produce the expected result.

however, I do agree that it's confused and such construction should be avoided using parenthesis to clarify
*(s_ptr++) or (*s_ptr)++
(again, I do consider both wrong as no dereference is needed, and do wonder why OP reached such solution)

edit: an alternative to increment the pointer would be to use array notation: s_ptr[count].number


> In ShowWidgets, you need to move s_ptr++ to AFTER the "}". (move line 115 to line 117).
if the condition succeed, the pointer is incremented
if the condition fails, the loop is terminated
however, there's one caveat, s_ptr->number is not initialised for all the elements of the array (there is no constructor for Widget that sets it to 0)
