Chapter 11: Problem 25

Assume a class named Dollars exists. Write the headers for member functions that overload the prefix and postfix + + operators for that class.

Short Answer

Expert verified

Answer: The function headers for overloading the prefix and postfix ++ operators in a class named Dollars are: 1. Prefix ++ operator: `Dollars& operator++();` 2. Postfix ++ operator: `Dollars operator++(int);`

Step by step solution

Declaration of the class Dollars

First, create the class named Dollars: ```cpp class Dollars { // Class content }; ```

Prefix ++ operator overloading

To overload the prefix ++ operator, declare a member function that returns a reference to Dollars and takes no parameter. Inside the class definition, add: ```cpp Dollars& operator++(); ```

Postfix ++ operator overloading

To overload the postfix ++ operator, declare a member function that returns a Dollars object and takes an integer parameter (unused) as a convention to indicate it is a postfix operator. Inside the class definition, add: ```cpp Dollars operator++(int); ```

Complete class with overloaded operators

Finally, the complete class with overloaded ++ operators will look like this: ```cpp class Dollars { public: Dollars& operator++(); // Prefix ++ operator Dollars operator++(int); // Postfix ++ operator // Other class content }; ```
