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,

WebHere is an example: C = A << 2; // left shift A by 2. Bit Shift Operator (Left) The value of C becomes 0xEC or in binary 1110 11 00 after shifting 2-bits to the left.
