This is solely symmetric with pointers to const, including the fact that the compiler does many of the examining at compile-time, which implies const doesn’t slow down your system and doesn’t demand you to jot down excess exam-conditions to check points at runtime.
Even when the language outlawed const_cast, the only way in order to avoid flushing the register cache throughout a const member
The origin of C is carefully tied to the event on the Unix operating system, initially implemented in assembly language on the PDP-7 by Dennis Ritchie and Ken Thompson, incorporating numerous ideas from colleagues. Inevitably, they chose to port the working system to the PDP-11.
