Operator book must be a non static member function

The this pointer is a special builtin pointer that is automatically passed as a hidden argument to all non static member functions. Study 40 terms computer science flashcards quizlet. Calling a member function of class x on an object of any other type invokes undefined behavior. Within the body of a nonstatic member function of x, any idexpression e e. They offer better flexibility, which is not provided by the member function of the class. Any operator defined for a class has to take at least one argument of that class type. The difference between member function and friend function is that the member function takes argument explicitly. The assignment operator must be a nonstatic member function and must have exactly one parameter.

On the contrary, the friend function needs the parameters to be explicitly. Most overloaded operators may be defined as ordinary nonmember functions or as class member functions. A nonmember operator has two important main benefits. In case we define above function as nonmember function of a class then we would have to pass two arguments for each operand as follows. A nonmember operator has an explicit argument of that class type. I have a function prototype inside a public class access specifier. Thanks for contributing an answer to stack overflow. The this pointer is a special builtin pointer that is automatically passed as a hidden argument to all nonstatic member functions. Implicit conversions of the right and the left side of the operator invocation.
