It is said in Stroustrup
"An object constructed by explicit or implicit use of a constructor is automatic and will be destroyed at the first opportunity.".

So if I define a new object of any class using a new function.

Will it still be considered automatic and be deleted ?

or would it be saved in the heap such that it will be deleted only using delete
command ?

className objName = new(className); //this is what I have in mind.

I guess something like:

void function (){
class {...} a;

// use a here
}

a is automatic object that constructed and destructed in scope of function.
