Introduction to OR Operator

Explore the basics of the Bitwise OR operator, understanding its behavior and bit-level computations. This lesson helps you grasp how to use the | operator to compare bits and solve related coding problems efficiently.

We'll cover the following...

What is the Bitwise OR operator?

This is the same as the OR gate we studied in the digital electronics chapter, as shown below:

The Bitwise OR operator is denoted by |. When an OR gate is given with two inputs, the corresponding outputs will be:

  • If two input bits are 0, the output is 0.
  • In
