WebMay 15, 2024 · 1. 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). The proposed solution is that we should use 1 bit matrix (element type is 1 bit). WebThere are two main differences between bitset and vector. First, the size of a bitset cannot be changed: bitset's template parameter N, which specifies the number of bits in the bitset, must be an integer constant. Second, bitset is not a Sequence; in fact, it is not an STL Container at all. Matt Austern has a nice article on its use.
