# What is a rules for defining a constructor

The rules for constructor creation can be summarized as follows:\
•A constructor must have the same name as the class name.•A constructor does not return anything, not even a void type.•A constructor may take zero or more arguments.•By default, the compiler provides a no-argument constructor.•If you provide any constructor—either a no-argument constructor or a constructor with arguments—the compiler does not provide a default constructor.\
Thanks
