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)) WebJan 6, 2024 · Problem statement: Write a C program to check if nth bit is set or not in a 32 bit integer.
