WebJul 30, 2024 · 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 to store the value. WebMar 24, 2015 · Setting the value of a bitfield member is easy. Just assign to the member the same way you would using a traditional bitfield. If asserts are enabled – such as in a debug build – and you try to assign a value that’s too large for the bitfield, an assert will occur at runtime. It’s meant to help catch programming errors during development. heat \u0026 light lamps ceiling fixture
