En cierto sentido un bitset es el contenedor más simple del mundo, contiene un número máximo N (determinado en el momento de su definición) de elementos tipo bit. With fixed width registers, many devices cram several bits of functionality into one register as a 'bitset'. C++ bitset to_ulong() is used to convert the contents of the bitset to an unsigned long integer. As decimal 11 can be expressed as bitwise 1011, the bit whose index is 3 (the fourth from the right) is set to 0, thus the result is 11 which corresponds to decimal 3. Bitset stores values in the form of 0 and 1. With C++11, we have std::bitset which is a nice abstraction for acting on the individual bits of a fixed size quantity. Removing from the std::array isn't necessary, since it will be overwritten if it doesn't exist in the bitset. hpp > # include < iostream > # include < random > int main (). C++ bitset all() function is used to test whether all bits from bitset are set or not. The function bitSet(11,2,true) returns 1111 which corresponds to decimal 15. bitset bitset is a feature-complete, generic and customizable dynamic bitset implementation in pure C.
