# Having trouble with bitwise logical operaors? Here's your one-stop solution

If you are one of those students who find it extremely difficult to handle bitwise logical operations, you are not alone. There are a lot like you who share the same problem. While struggling with a problem is one thing, you need to make sure that you donâ€™t remain stuck. When things are not going as planned, you always have some alternate options to choose from. Or, you can also change the way you approach the problem.

SThe bitwise operators are similar to the logical operators, except that they work on a smaller scale -- binary representations of data.

The following operators are available:

op1 & op2 -- The AND operator compares two bits and generates a result of 1 if both bits are 1; otherwise, it returns 0.

op1 | op2 -- The OR operator compares two bits and returns 1 if either of the bits are 1 and it gives 0 if both bits are 0 or 1.

op1^ op2 -- The EXCLUSIVE-OR operator compares two bits and generates a result of 1 if the bits are complementary; otherwise, it returns 0.

~op1 -- The COMPLEMENT operator is used to invert all of the bits of the operand.

op1 >> op2 -- The SHIFT RIGHT operator moves the bits to the right, discards the far right bit, and assigns the leftmost bit a value of 0. Each move to the right effectively divides op1 in half.

op1 << op2 -- The SHIFT LEFT operator moves the bits to the left, discards the far left bit, and assigns the rightmost bit a value of 0. Each move to the left effectively multiplies op1 by 2.

Note Both operands associated with the bitwise operator must be integers.

Bitwise operators are used to change individual bits in an operand. A single byte of computer memory-when viewed as 8 bits-can signify the true/false status of 8 flags because each bit can be used as a boolean variable that can hold one of two values: true or false. A flag variable is typically used to indicate the status of something. For instance, computer files can be marked as read-only. So you might have a \$fReadOnly variable whose job would be to hold the read-only status of a file. This variable is called a flag variable because when \$fReadOnly has a true value, it's equivalent to a football referee throwing a flag. The variable says, "Whoa! Don't modify this file."

When you have more than one flag variable, it might be more efficient to use a single variable to indicate the value of more than one flag.

This tool has now helped thousands of students get over the fear of solving boolean algebra equations. They have found the perfect tool that not just helps them solve the equations but also explain the concepts of truth table and the logic behind it.
