A ,bit, field can hold more than a single ,bit,; for example, if you need a variable to store a value from 0 to 7, then you can define a ,bit, field with a width of 3 ,bits, as follows − struct { unsigned int age : 3; } Age; The above structure definition instructs the ,C, compiler that the age variable is going to use only 3 ,bits, …

14/11/2005, · What's an efficient way to ,mask, a last 3 ,bits, of a 8-,bit, char and make them all zero? ,Bit,-shifting is possible but not sure if it is efficient enough. Example: 01011[010] --> 01011[000] Many or perhaps even most ,C, implementations use an eight-,bit, `char', but that is not actually guaranteed by the language, and implementations using wider `char'

Anonymous ,bit, fields — that is, ,bit,-field members with no identifier — can be used for padding. Note. An unnamed ,bit, field of width 0 forces alignment of the next ,bit, field to the next type boundary, where type is the type of the member. The following example declares a structure that contains ,bit, fields:
