We had study
about data type in all computers programming language, so I know about these
data types. Every computer programming language has its own set of data types.
There are two
types of data types.
We have discussed
about derived / composite data type. These data type derived from the basic /
primary data type.
1. Array:- generally variable are
capable of holding pnly one value at a time . if you want to store more than
value at a time in a single variable we use arrays. Arrays is also sequence of object.
Eg:- int num [5];
Reserve a sequence of five location of 2 bytes, each for storing interger
num[0], num[1], num[2], num[3], num[4];
2. Pointer: - is used to store the
address of memory location.
Example:- int n;
int *ptr;
//pointer to an interger
The following statement assign the address location of the variable ‘n’
to ‘ptr’ and ‘ptr’ is a pointer to ‘n’.
ptr=&n;
3. Structure: - structure is collection of
different type of variable.
Example: - structures of employee data i.e. name, salary, age, address
e.t.c.
4. Union: - union is collection of
variables of different types sharing common memory space.
5. Enumerated: - (enum) its members are
the constant that are written as.
Identifiers data type through they g=have signed integer values that can
be assigned to corresponding enumeration variables.
Enum tag {memebr1, member2, member3…….membern};
Example:- enum color{red, blue, green, white};
