C pointers can be defined as a variable, pointing towards the address of a value. When a pointer refers to the address of another pointer, it is called as Pointer to Pointer in C.
Syntax:
Data_type **variable_Name;
Example:
#include<stdio.h> void main() { int n = 60784; int *a; int **b; a = &n; b = &a; printf("n = %d \n",n); printf("a = %x \n",a); printf("b = %x \n",b); printf("&n = %x \n",a); printf("&a = %x \n",b); } |
Output
n = 60784 a = fef63734 b = fef63738 &n = fef63734 &a = fef63738 |
