Features of pointers:
- a) Pointers are efficient in handling data and associated with array.
- b) Pointers are used for saving memory space.
- c) Pointers reduce length and complexity of the program.
- d) Pointer helps to make letter use of the available memory.
- e) Since the pointer data manipulation is done with address, the execution time is-faster.
- f) Two-dimensional and multidimensional array representation is easy in pointers.
- g) Pointers allows for references to function, this may facilitate passing of function as arguments to other functions.
