< C++ Language | Objects
Programming custom implementations for operators is the mechanism for allowing a custom C++ class to be used as a "value type" (which then can behave similar to built-in primitive types like int
).
For example, client code expects to be able to do int iX = iY + iZ + 9;
; if you want your custom class to also behave that way, then define its const CRType CRType::operator+(const CRType& aroRhs) {body}
.
