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.
void function (){
class {...} a;
// use a here
}
a is automatic object that constructed and destructed in scope of function.
