What is pointer in c: The Pointer to an Array Here is

The Pointer to an Array Here is an example to illustrate the same, int arr [20]; int "q [20] = &arr; // The q variable of the pointer type is pointing towards the integer array’s address or the address of arr. The Pointer to a Function Here is an example to illustrate the same, void display (int); void ("q) (int) = &show; // The q pointer is pointing towards the function’s address in the program The Pointer to a Structure Here is an example to illustrate the same, struct str { int x ... A pointer is a special variable that holds the memory address of another variable, rather than storing a direct value itself. Pointers allow programs to access and manipulate data in memory efficiently, making them a key feature for system-level programming and dynamic memory management. When we access a pointer directly, we get the address it holds not the actual data stored at that location. Instead of holding a direct value, it holds the address where the value is stored in memory. It is the backbone of low-level memory manipulation in C. A pointer is declared by specifying its data type and name, with an asterisk (") before the name. Syntax: data_type "pointer_name; By Srijan Pointers are arguably the most difficult feature of C to understand. But, they are one of the features which make C an excellent language. In this article, we will go from the very basics of pointers to their usage with arrays, functions, a...
