Tag: Can C++ class have no constructor?

It is possible for a class to have no constructor . (An important distinction to draw here is that the JVM does not require all class files to have a constructor; however, any class defined in Java does have a default constructor if a constructor is not explicitly declared.

In C++, the compiler creates a default constructor if we don’t define our own constructor. In C++, compiler created default constructor has an empty body, i.e., it doesn’t assign default values to data members.

If your class has no constructors, C++ will automatically generate a public default constructor for you . This is sometimes called an implicit constructor (or implicitly generated constructor). The Date class has no constructors.5 Eyl 2007
