Why extra object when initialising vector of custom class objects

Question

Hello

Please refer code below :

When I initialise five object of class without any argument to constructor, it seems ok

If I decide to go with parametric constructor for 5 objects, why am I able to observe 6 destructor calls ?

Answer 1

This is weird, where are you observing the 6th call ?

Answer 2

Due to some issue currently at sololearn on mobile app for Android, I cannot check your entire code as still only having first few lines

However I got idea of increasing count for each constructor call.

Doing so also, got the count of constructors as 6 as updated in code. So , still issue of additional constructor call is there..

And I never thought of making member variables as inline... What's the advantage of same ? Only inline functions I have seen earlier but not member variables as inline
