WebOct 25, 2024 · The above representation of ‘date’ takes 12 bytes on a compiler whereas an unsigned int takes 4 bytes. Since we know that the value of d is always from 1 to 31, and the value of m is from 1 to 12, we can optimize the space using bit fields. Declaration of bit-fields in C Bit-fields are variables that are defined using a predefined width or size. WebC - Unions. A union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose.
