member function.
A function that operates on an object that is passed as an implicit parameter named

To call a function “on” an object, in order to pass the object as an implicit parameter.

The object on which a member function is invoked. Inside the member function, we can refer to the current object implicitly, or by using the keyword

this.

this is a pointer, which makes it difficult to use, since we do not cover pointers in this book.
interface.
A description of how a function is used, including the number and types of the parameters and the type of the return value.
function declaration.
A statement that declares the interface to a function without providing the body. Declarations of member functions appear inside structure definitions even if the definitions appear outside.

The body of a function, or the details of how a function works.
constructor.
