How to set nth bit
WebTo set a bit or Nth bit in C language, We use the Bitwise OR operator with the bitwise Left shift operator. The SETting an Nth bit means, We need to make the Nth bit as One (1). So if the bit in the Nth position is Zero (0), Then we need to change it to One (1). WebJan 24, 2016 · Logic to set nth bit of a number Input number from user. Store it in some variable say num.

Example Code WebJan 27, 2024 · std:: bitset C++ Utilities library std::bitset Defined in header template< std::size_t N > class bitset; The class template bitset represents a fixed-size sequence of N bits. Bitsets can be manipulated by standard logic operators and converted to and from strings and integers.
WebTo access the nth bit from right, we can keep dividing the number by 2, n times and then the remainder is our answer. But this approach is lengthy as we would have to write while loop. Instead we can solve this in one step, we would shift the bits of the number by n-1, so that the bit we wish to obtain is now the last bit of the number.
