A structure or a C++ class can contain bit fields that allow you to access individual bits. You can use bit fields for data that requires just a few bits of storage. A bit field declaration contains a type specifier followed by an optional declarator, a colon, a constant expression, and a semicolon.

Bit fields are important for two main reasons: 1.Allows you to manipulate individual bits using a field name.(just as AMOGHA. A. K. has said) 2.unnamed bit fields are used to align the data in structs in a machine dependent way

Finally come up with use case when bit field can be applied to save memory https://code.sololearn.com/c7L891KF9TXI/?ref=app Thanks all of you for your time and help

But does this help in structure padding ? If not, what purpose it helps ? And accessing memory is not in our hand.. Isn't it?
