We do not put up with the delusion that every a person of these guidelines could be correctly placed on each code base. Upgrading previous programs is difficult.
const X* const p means “p can be a const pointer to an X that is constâ€: you could’t change the pointer p
This can be entirely symmetric with pointers to const, such as the indisputable fact that the compiler does many of the checking at compile-time, which means const doesn’t slow down your plan and doesn’t need you to write excess take a look at-cases to check things at runtime.
Option: Occasionally older code can’t be modified because of ABI compatibility needs or insufficient assets.

Use algorithms which have been suitable for parallelism, not algorithms with pointless dependency on linear evaluation
How most effective to get it done depends upon the code, the tension for updates, the backgrounds on the builders, along with the accessible Software.
Conceptually you'll be able to picture that const std::string, for instance, is another class than ordinary std::string,
Take note: There exists an extremely unlikely mistake that may come about with const_cast. It only happens when 3 very unusual
