PCD
For example:
enum colors{red, green=2, blue};
// red will be 0, green will be 2 and
// blue will be 3
Struct structure type: creates a collection of one or more
variables, possibly of different types, grouped together as a
single unit.
struct [ * ] [id] {
type-qualifier [ * ] id
One or more,
semi-colon
[:bits];
} [id]
Zero
or more
separated
For example:
struct data_record {
int
int
int
a[2];
b : 2; /*2 bits */
c : 3; /*3 bits*/
int d;
} data_var;
//data_record is a structure type
//data _var is a variable
Union type: holds objects of different types and sizes, with the
compiler keeping track of size and alignment requirements. They
provide a way to manipulate different kinds of data in a single
area of storage.
union [ * ] [id] {
type-qualifier [ * ] id
One or more,
semi-colon
separated
[:bits];
} [id]
Zero
or more
For example:
union u_tab {
int ival;
long lval;
float fval;
24
};
// u_tag is a union type that can hold a float
