Tag: Can a class have no constructor C++?

Meaning: always write an empty constructor in your entity. But Java always gives you this empty constructor when you don’t redefine it (write an other one with parameters).

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.

Answer: C++ Empty constructor necessity depends upon class design requirements. We know that C++ class constructor is called when we create an object of a class. If a class is not required to initialize its data member or does not contain data member, there is no need to write empty constructor explicitly .10 Eki 2016

The body of the constructor is defined inside the curly brackets { } after the parameter list. In the constructor example above the constructor has no operations inside the constructor body. It is said to be an “empty” constructor .
