A truth table is a two-dimensional array with 
columns. The first 
columns correspond to the possible values of 
inputs, and the last column to the operation being performed.
The rows list all possible combinations of inputs together with the corresponding
outputs. For example, the following truth table shows the result of the binary AND operator acting on two inputs 
and 
,
each of which may be true or false.
