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.
