C solved programs/examples on Bitwise Operators

This section contains solved programs on Bitwise Operators with output and explanation, here we will learn how and why to use bitwise operators by demonstrating relevant examples.

The operators which we are going to use in these examples are bitwise AND (&), bitwise OR (|), Left shift operator (<<), right shift operator (>>) and more.

List of bitwise operator example programs in C

Here is the list of some of the C language programs based on Bitwise operators.
