Welcome to Mktaba Question, where you can ask questions and receive answers from other members of the community. Explanation: Destructors Are not called for automatic objects if the program terminates with a call to function exit or function abort. We can call an overloaded constructor from another constructor using this keyword but the constructor must be belong to the same class, because this keyword is pointing the members of same class in which this is used. Please help me with the Classification of Assets. If no user-defined destructor exists for a class and one is needed, the compiler implicitly declares a destructor.
In constructor loading, we create multiple constructors with the same name but with different parameters types or with different no of parameters. , .
