Applications and advantages of Pointers

Except for a handful, most C programs may be written with or without pointers. Then there's the question of "why utilize pointers if you don't have to?" These are the following reasons why the pointers are regarded as valuable programming tools:

  • (i) Pointers make programs easier to understand and shorter.
  • (ii) ) Pointers are used for memory allocation and deallocation during program execution. As a result, pointers are used to handle dynamic memory.
  • (iii)Pointers improve a program's speed of execution.
  • (iv) When navigating over arrays and character strings, pointers are helpful. The strings are also character arrays with the null character ('O') at the end.
  • (v) Pointers may be used to refer to a variety of objects, including variables, arrays, functions, structures, and so on. However, unlike C++, the C language lacks the idea of references. As a result, pointers are used as a reference in C.
  • (vi) Strings are stored via pointers, which saves memory.
  • (vii) As parameters to a function, pointers can be used to convey arrays, texts, functions, and variables.
  • (viii) ) Passing arrays through pointers saves a lot of memory since we are simply passing on the array's address rather than all of the elements, which would require passing on copies of all of the items, which would take up a lot of memory.
  • (ix) Pointers are used to create various data structures, including linked lists, queues, and stacks.
