Hero Electric Worker Interview Questions and Answers

Q1. What is a bit field
Ans. 
A bit field is a data structure used in computer programming to store multiple boolean values compactly in a single variable.
• A bit field allows individual bits within a byte, word, or other data structure to be accessed and manipulated.

• It is often used to optimize memory usage by packing multiple boolean values into a single variable.

• For example, a struct representing a set of flags can be defined using a bit field to
