Answer / rams
Bit fields are used to restrict the size of a structure member. we can reduce the size of a structure member as a result no wastage of bits. suppose if i want to store date generally it is between 1 to 31 we can store it in 5 bits only.
bit fields can be used only with in structure.
ex:struct st
{
char date:5;
};
