C++ Primer Plus, Fourth Edition

Chapter 8. ADVENTURES IN FUNCTIONS

In this chapter you learn

• Inline functions

• Reference variables

• How to pass function arguments by reference

• Default arguments

• Function overloading

• Function templates

• Function template specializations

With the last chapter under your belt, you now know a lot about C++ functions, but there's much more to come. C++ provides many new function features that separate C++ from its C heritage. The new features include inline functions, passing variables by reference, default argument values, function overloading (polymorphism), and template functions. This chapter, more than any other you've read so far, explores features found in C++ but not C, so it marks your first major foray into plus-plussedness.
