pointer to a pointer
Basic C Program for Pointer to a Pointer
A pointer variable stores the address of a value. Similarly, a pointer to a pointer stores the address of the pointer variable. Pointer to a pointer is executed making use of
**.
Below is a program on pointer to a pointer.
int var; is a integer variable which stores value.int *ptr; is a pointer variable which stores the address of an integer variable.int **pptr; is a pointer to a pointer variable which stores the address of a pointer variable.#include<stdio.h>
int main()
{
printf("\n\n\t\tStudytonight - Best place to learn\n\n\n");
int var;
int *ptr;
int **pptr;
var = 50;
// take the address of the variable var
ptr = &var;
// taking the address of ptr using address of operator-&
pptr = &ptr;
// take the value using the pptr
printf("\n\nValue of var = %d\n\n", var);
printf("\n\nValue available at *ptr = %d\n\n", *ptr);
printf("\n\nValue available at **pptr = %d\n\n", **pptr);
printf("\n\n\t\t\tCoding is Fun !\n\n\n");
return 0;
}Output:
