Definition of Pointer in C Every variable is stored in some memory location, and that memory location has an address. A pointer is a variable that stores the memory address of variables, functions, or other pointers. A pointer is a derived data type that can store the memory address of ...
The significance of pointers in C is the flexibility it offers in the programming. Pointers enable us to achieve parameter passing by reference, deal concisely and effectively either arrays, represent complex data structures, and work with dynamically allocated memory. Although a lot of programming ca...
