WebBitwise Operators: There are different bitwise operations used in the bit manipulation. These bit operations operate on the individual bits of the bit patterns. Bit operations are fast and can be used in optimizing time complexity. Some common bit operators are: WebIn C, bitwise OR operator ( ) used to set a bit of integral data type. As we know that (Bitwise OR operator) evaluates a new integral value in which each bit position is 1 only when operand’s (integer type) has a 1 in that position. In simple words, you can say that “Bitwise OR ” of two bits is always one if any one of them is one. That means,
