Default Member Initializers for Bit Fields
Learn how to default initialize the members of a bit field with an example.
First of all, what is a bit field? Here is the definition from Wikipedia: “A bit field is a data structure used in computer programming. It consists of a number of adjacent computer memory locations which have been allocated to hold a sequence of bits, stored so that any single bit or group of bits within the set can be addressed. A bit field is most commonly used to represent integral types of known, fixed bit-width.”
