What are Bitfields What is the use of bit fields in a structure ...

WebC allows a structure to have fields which are smaller than a char (8 bits). Specifically, they can have fields as small as a single bit. These fields are called bit fields and their type is either int, signed int or unsigned int. You should always specify either signed or unsigned because the type of int in a bit field is implementation ... WebThe following two examples demonstrate the use of bit fields to reduce memory consumption of certain applications. In the first example we create a compressed ‘bit’ struct and on the second we create a weird struct representation for bytes to show that the size of that struct is significantly less that the original one.
