Pointers to Pointers and Multilevel Indirection in C

 Pointers to Pointers and Multilevel Indirection in C

Pointers to pointers allow you to create multilevel indirection and handle complex data structures that involve multiple levels of memory references.

#include <stdio.h>

int main() {

    int num = 42;

    int* ptr = &num;

    int** ptrToPtr = &ptr;

    int*** ptrToPtrToPtr = &ptrToPtr;

    printf("Value: %d\n", ***ptrToPtrToPtr);

    printf("Address: %p\n", ***ptrToPtrToPtr);

    return 0;

}
