WebMar 25, 2016 · C++ bitset and its application. A bitset is an array of bools but each boolean value is not stored in a separate byte instead, bitset optimizes the space such that each … Webbitset<365> is a binary number with 365 bits available, and it supports most of binary operations. The code above changes into simple: code Some functions differ, e.g. x.count () instead of __builtin_popcount (x) but it's only more convenient.

In micro controller development, some times we need to use 2-dimentional array (matrix) with element value of [0, 1] only. That means if we use 1 byte for element type, it wastes the memory greatly (memory of micro controller is very limited).
