Chapter 19: Operator Overloading

Chapter 19

Operator Overloading

After completing this chapter, you will be able to:

• Implement binary operators for your own types.

• Implement unary operators for your own types.

• Write increment and decrement operators for your own types.

• Understand the need to implement some operators as pairs.

• Implement implicit conversion operators for your own types.

• Implement explicit conversion operators for your own types.

You have made a great deal of use of the standard operator symbols (such as + and –) to perform standard operations (such as addition and subtraction) on types (such as int and double). Many of the built-in types come with their own predefined behaviors for each operator. You can also define operators for your own structs and classes, which is the subject of this chapter.
