In C++, using `std::bitset` in `constexpr` contexts allows you to perform compile-time computations on fixed-size sequences of bits. This can be particularly useful for applications that require bit manipulation, such as implementing flags or managing sets of binary data.
Here's an example of how to utilize `std::bitset` in constexpr contexts:
#include
#include
constexpr std::bitset<8> createBitset() {
return std::bitset<8>(0b10101010);
}
int main() {
constexpr auto myBitset = createBitset();
std::cout << myBitset << std::endl; // Output: 10101010
return 0;
}
