u About Logical Operations
• A logical operation always produces either 0 or 1 as its result.
• The following table shows all of possible results that can be produced by AND, OR and XOR
operations.
Value or Expression A
A ≠ 0
A ≠ 0
A = 0
A = 0
• The following table shows the results produced by the NOT operation.
Value or Expression A
A ≠ 0
A = 0
What is the logical AND of A and B when A = 3 and B = 2?
A AND B = 1
