cert-dcl21-cpp

This check flags postfix operator++ and operator-- declarations if the return type is not a const object. This also warns if the return type is a reference type.

This check corresponds to the CERT C++ Coding Standard recommendation DCL21-CPP. Overloaded postfix increment and decrement operators should return a const object.
