WebGet Bit: What Get Bit does is returns if the it at i th position is 0 or 1. We know ANDing a number with 1 gives back the same number, since 0 & 1 = 1 and 1 & 1 = 1. What we can do is: if we are interested in knowing what i th is, we can form a number that has 1 at i th bit and 0 in all other bits.

WebJul 1, 2012 · The idiomatic way to extract a bit is either (x >> i) & 1 which would also work analogously for more than one bit, or x & (1 << i) if you just want to test a single bit. Note that in C x must not be negative (preferably declared unsigned), and if x is longer than an int you need to specify that 1 is also that long in the second one. WebFeb 18, 2024 · Get Bit: This method is used to find the bit at a particular position(say i) of the given number N.
