Destructors C++

Well, there's something I don't clearly understand : What does exactly the destructor do to the instance of a class? I mean, it's called right after the Object is created, but the Object's still usable. So what does it exactly destroy?

Destructors are called when objects are destroyed. For example: class A{ ~A(){cout << "Destroyed"} } When you create an object: int main(){ A a; } The program will create the object and destroy it at the end of the program. When it is destroyed, it will output "Destroyed". I think you may have been confused with constructors, which are those run when an object is created. For example: class B{ B(){cout << "Constructed";} } When you create an instance of B, the constructor will be called, outputting "Constructed" and then destroyed promptly afterwards at the end of the program. Hope this helped! 😉
