Exam 11: Friends, Overloaded Operators, and Arrays in Classes

Since accessor functions in a class do not modify or mutate the data members of the object, the function should have the __________ modifier.

You cannot create new operators such as the quote).

How many members data and functions) does the following class have? Class Rational { Public: Rational); Rationalint numer, int denom); Rationalint whole); Int getNumerator); Int getDenominator); Friend void displayostream& out, const Rational& value); Private: Int numerator; Int denominator; };

If c is a character variable that contains a digit, what does the following function return? Int digit_to_intchar c) { Return intc) - int'0')); }

What member functions do you need to allow the compiler to perform automatic type conversions from a type different than the class to the class?

Putting the keyword const after the function declaration guarantees __________________________

All operators can be overloaded.

If a given task being performed by a function involves one object, then that function should normally be a __________ function.

How many parameters are there in a unary operator implemented as a friend?

If we have a full selection of accessor and mutator functions, why would we have friend functions?

Why are the extraction and insertion operators always implemented as friends of the class rather than as members of the class?

Write the function declaration for an assignment operator for a class named myClass

In order to do automatic type conversion for your class, you would write _________

In an overloaded insertion or extraction operator, which object should be the first parameter, the stream or the object of the class?

Write the function declaration for a destructor for a class named myClass

Given the following function declaration, Friend void displayconst myClass& object); Which is the correct header for the definition of the function?

Which of the following statements are true?

If you have mutators and accessors, you should not have friend functions also

When overloading an operator, which of the following is true?

A _________ function is not a member of the class, but has access to the private members of the class.
