Compare Between Array And Structure

Compare Between Array And Structure

Array

•        I.            An Array is the collection of related data element of same types.
•      II.            An Array is a derived data types.
•   III.            An Array behaves like a built in data type we can declared array variables and uses it.
•   IV.            Array allocates static memory and use index subscript for accessing elements of array. Structure allocates Dynamic memory and used operator for accessing the member of structure.
•     V.            An array behaves like a built in data types All we have to do is to declare an array variable and use it.
•   VI.            Array name is the pointer to the 1^st elements of its.
• VII.            Data type (int, Char, Etc) keyword is used to define Array.
• VIII.            Eg ( Int a[50].

Structure

•        I.            A Structure have a element of different types
•      II.            A structure is a user define type.
•   III.            First we have to define an structure and then declare the variable of that type.
•   IV.            Structure name is not pointer.
•     V.            Struct  keyword is used.
•   VI.            Each member of structure is assigned its own unit storage. It takes more memory space then of union.
• VII.            All the member of Structure can be access at any time at any point of time.
• VIII.            EG

Struct S {

Char a;

Int i;

}

St;
