WebSep 23, 2014 · You have to invert your mask because logical AND ing with a 1 will maintain the bit while 0 will clear it... so you'd need to specify a 0 in the location that you want to clear. Specifically, doing 1 << i will give you a mask that is 000...010..000 where the 1 is in the bit position that you want, and inverting this will give 111...101...111.

WebMar 28, 2014 · Assuming 32 bit integers, the case of 1 << 31 leads to undefined behavior. Generally, in 99.9% of the cases it doesn't make any sense whatsoever to use bitwise operators on signed integers. If you wish to write safe … WebJun 25, 2009 · Actually, I've gone one step further here, and implemented a class called Flags that provides member functions for manipulation of bit flags. My base class uses atomic operations (handy when setting and testing in different threads), and I've even derived from it in a few cases to store flag state in the Windows registry automatically …

WebMay 27, 2024 · Given a non-negative number n and two values l and r. The problem is to set the bits in the range l to r in the binary representation of n, i.e, to unset bits from the rightmost lth bit to the rightmost r-th bit. Constraint: 1 <= l <= r <= number of bits in the binary representation of n. Examples : WebSetting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x …
