1. Bitwise operators in C language Operatorsignificancerule & Bitwise and All 1s get 1, and 0s get 0 I Bitwise or 1 is 1 and all 0s are 0 ^ Bitwise exclusive or Same as 0, different as 1 ~ Negate 1 becomes 0, 0 becomes 1 << Shift left High bits are discarded, low bits are...
C Bitwise Operators& binary bitwise AND ^ binary bitwise exclusive OR (XOR) | binary bitwise inclusive OR ~ unary bitwise complement (NOT)An operand is the variable or value on which the operator acts. Bitwise operators perform the given operation on each bit in the operand. Binary means the...

To access the individual bits of a bit field, you can use the bitwise operators (&, |, ^, and ~). For example, to check if the third bit of the flags variable is set, you can use the following code: if (flags & 4) { // The third bit is set } ...
