W8063 Overloaded prefix operator 'operator' used as a postfix operator (C++)

Go Up to Compiler Errors And Warnings (C++) Index

(Command-line option to suppress warning: -w-pre)

The C++ specification allows you to overload both the prefix and postfix versions of the ++ and -- operators.

Whenever the prefix operator is overloaded, but is used in a postfix context, the compiler uses the prefix operator and issues this warning.

This allows older code to compile.
