In C programming language, a pointer is a variable that stores the memory address of another variable. It is a powerful feature of C and is extensively used in many programming tasks, such as dynamic memory allocation and passing arguments to functions by reference. Pointers allow us to directly manipulate the memory, which can lead to efficient code, but also makes it easier to introduce bugs if not used carefully.
Pointers are declared by using the * symbol before the variable name, and they can be initialized to the memory address of another variable using the & operator. Once a pointer is initialized, it can be used to read or modify the value stored at that memory location.
Syntax to define pointer in C:
type *pointer_variable;
Example:
int *p
int x = 42;
int *p = &x;
printf("Value of x=%d",*p);
