WebAug 5, 2024 · Bitwise operators are the operators that work a bit level in the program. These operators are used to manipulate bits in the program. In C, we have 6 bitwise operators − Bitwise AND (&) Bitwise OR (OR) Bitwise XOR (XOR) Bitwise left Shift (<<)/p> Bitwise right Shift (>>) Bitwise not (~) WebTo reset a bit, the bit_reset () function uses both the bitwise ^ (exclusive or) and & (and) operators. These operators help to isolate the individual bit and set only that bit to 0. …

If the first bit (which corresponds to a value of two) is to be ckecked, one would use result = flags & 00000010 and afterwards check result, which will be zero if the bit is not set and nonzero if the bit is set. More generalized, one could use result = flags & (00000001 << i) where << denotes the shift operator to check the i -th bit. Share WebIn C programming language, a Hexadecimal number is represented by preceding with "0x" or "0X", thus the value in Hexadecimal can be written as "0x64" (which is equivalent to 100 in Decimal ).
