Since we have to turn it to 1 if its zero and leave it as it is if its 1, its … WebThe idea is to use bitwise << and & operators. Using the expression 1 << (k - 1), we get a number with all bits 0, except the k'th bit. If we do bitwise AND of this expression with n, i.e., n & (1 << (k - 1)), any non-zero value indicates that its k'th bit is set. For example, consider n = 20 and k = 3. 00010100 & (n = 20) 00000100 (1 << (3-1)) WebJun 12, 2024 · Here is the source code of the C Program to set the nth bit of a number.
