C++ : how can I copy 2 bits from one int to another?

WebTo get the least-significant bits (LSB) of a value, use the following method: public static int GetLSB(int intValue) { return (intValue & 0x0000FFFF); } This technique can easily be modified to work with other sizes of integers (e.g., 8-bit, 16-bit, or 64-bit); this trick is shown in the Discussion section. Webis a static integer constant (or constexpr in C++11) giving the number of bits (since unsigned is stored in base 2, it gives binary digits).

WebThe most common representation of a positive integer is a string of bits, using the binary numeral system. The order of the memory bytes storing the bits varies; see endianness. The width or precision of an integral type is the number of bits in its representation. WebSo, bit_value = ( (uint8_variable>>BIT_NEEDED)&1) So this would shift the bit you need in LSB position, and the & operator would mask the other bits. Example: uint8_variable = …
