Legal Notices Open table of contents WebTo turn certain bits on, the bitwise ORoperation can be used, following the principlethat Y OR 1 = 1and Y OR 0 = Y. Therefore, to make sure a bit is on, ORcan be used with a 1. To leave a bit unchanged, ORis used with a 0. Example: Masking onthe higher nibble(bits 4, 5, 6, 7) while leaving the lower nibble (bits 0, 1, 2, 3) unchanged. foam rectangle plates

WebA 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 to store the value.
