In C++, casting away constness of a variable is achieved using which keyword?

static_cast
reinterpret_cast
const_cast
dynamic_cast

The correct answer is: const_cast

C++ provides four types of casting - static_cast, reinterpret_cast, const_cast, and dynamic_cast. In this case, the keyword used to cast away constness of a variable is const_cast. Option A, static_cast, performs a general type conversion, option B, reinterpret_cast, converts any pointer into any other pointer type, and option D, dynamic_cast, is used for casting within a class hierarchy. Since none of these options specifically target constness, they are not the correct answer for this question.
