A pointer is a derived data type in C.
·
Pointer
is a variable which stores the add of another variable.
·
Pointer
contain memory address as their value.
·
Pointers
can be used to access & manipulate data stored in the memory.
Benfits of pointers:–
1. pointers are more efficient in handling arrays &
data tables.
2. Pointers can be used to return multiple values from a
function via function arguments.
3. pointers permit references to functions & there by facilitating passing of
functions as arguments to other functions .
4. The use of pointers arrays to character strings
results in saving of data storage space in memory.
5. Pointers allow C to support dynamic memory management.
6. Pointers provide an efficient tool for manipulating
dynamic data structures. Such as structures, linked lists, queues, stacks & trees.
7. Pointers reduce length & complexity of programs.
