Bitwise operator programming exercises and solutions in C

Bitwise operators are used extensively in programming whenever we need to operate on bit level of the value. Bitwise operator works on each bit of the data. There are operators are used for multiple purposes such as - setting or resetting flag values, testing the status of bit, complementing, or shifting bits either to left or right. So whenever you need to work on the lowest level of data we use bitwise operators. There are six types of bitwise operators:

1. Bitwise AND operator &
2. Bitwise OR operator |
3. Bitwise XOR operator ^
4. Bitwise complement operator ~
5. Bitwise left shift operator <<
6. Bitwise right shift operator >>

Below is a set of programming exercises that can be used by a beginner or an intermediate programmer to master their skills on bitwise operator.
