(^ in C++/CLI is used to declare CLI object pointers; ^ still doubles as bitwise xor (not bitwise not))

: The ^ operator was never used for bitwise not in C or C++ (the bitwise not operator is ~). The binary ^ is xor, and remains to have that function in C++/CLI. However in C++/CLI, ^ can also be used in declarations to define a CLI object pointer (i.e. a pointer to a "managed" object). This is quite similar to the double use of * to mean both multiplication (2*5) and declaration of pointer (int* p), except that * can in addition be used as unary dereference operator (*p), which I don't think is possible with ^. --[[Special:Contributions/132.199.97.100|132.199.97.100]] 14:07, 6 August 2010 (UTC)
