Chapter 11: Problem 27

Assume a class named Length exists. Write the header for a member function that overloads the stream insertion \(<<\) operator for that class.

Short Answer

Expert verified

Based on the provided step-by-step solution, the header for the member function in the Length class that overloads the stream insertion operator << is: ```cpp std::ostream& operator<<(std::ostream& out); ```

Step by step solution

Determine the return type

The stream insertion operator should return an ostream reference, which allows for chaining multiple stream insertions.

Determine the function name

Since the function will be overloading the << operator, we will use the keyword "operator<<" as the function name.

Determine the parameters

The function should have one parameter of type ostream&, since this is what we will be inserting the Length object into.

Write the header for the member function

Considering the return type, function name, and parameters, the header for the member function will be: ``` std::ostream& operator<<(std::ostream& out); ```
