That too is not nearly as efficient as what a for_each method implementation could do.

WebA bit array (also known as bitmask, bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits.It can be used to implement a simple set data structure.A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. A typical bit array stores kw bits, where w is the number of bits in the unit of … Webstd:: popcount. std:: popcount. Returns the number of 1 bits in the value of x . This overload participates in overload resolution only if T is an unsigned integer type (that is, unsigned char, unsigned short, unsigned int, unsigned long, unsigned long long, or an extended unsigned integer type). diabetic smart snacks

(2) single bit Flips the bit at position pos. Parameters pos Order position of the bit whose value is flipped. Order positions are counted from the rightmost bit, which is order position 0. If pos is equal or greater than the bitset size, an out_of_range exception is thrown. diabetic smart programme
