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. WebThe variables defined with a predefined width are called bit fields. 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 …
