Checking whether a bit is on or off is known as masking. So, these two operations we have seen in Bitwise operations: left shift, masking and merging. All these operations we will use now for finding duplicates in a string.

WebAll data is stored in its binary representation. The logical operators, and C language, use 1 to represent true and 0 to represent false. The logical operators compare bits in two numbers and return true or false, 1 or 0, for each bit compared. Bitwise AND operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. WebNon-bitwise Logical Operators Note that the logical operators &&, , and ! work exactly the same as the bitwise values, but for exactly one bit. Internally, these operators map multi-bit values to a single bit by treating zero as a zero bit, and nonzero values as a one bit.

WebEvery bitwise operation will revolve around macros similar to AND_MACRO - you compare remaining values of a and b to the "mask" (which is "c" parameter). then add mask to the result in the if branch that is suitable for your operation. … WebApr 10, 2024 · A Bitwise And operator is represented as ‘&’ and a logical operator is represented as ‘&&’. The following are some basic differences between the two operators. a) The logical and operator ‘&&’ expects its operands to be boolean expressions (either 1 or 0) and returns a boolean value. The bitwise and operator ‘&’ work on Integral ...
