INTERVIEW QUESTIONS C++ C++ BASICS DETAILS

Question: In c++ have a default constructor ?

Answer: Yes C++ does have a default constructor provided by the compiler.In this case all the members of the class are initialized to null values.These values act as the default values.For eg: MyClass me;In the above case since the object is not initialized to any value so the default constructor will be called which will initialize the class with the default values.

Above answer is right, but remember If you write down one or more parametric constructor then If u want to create a object without any parameter then at that time compiler doesn't create the empty constructor, you must write down your own empty constructor.

yes..The point is, compiler by default creates the default constructor only and only if the class doesn't contain any constructor.
