WebMar 7, 2024 · The result of operator^ is the bitwise XOR value of the operands (after usual arithmetic conversions). There is an ambiguity in the grammar when ~ is followed by a type name or decltype specifier (since C++11): it can either be operator~ or start a destructor identifier). The ambiguity is resolved by treating ~ as operator~. how to make jam in thermomix
