Understanding Pointers in C by is a focused guide designed to demystify one of C's most challenging concepts through clear explanations and practical examples. Key Topics Covered
One of the most eye-opening sections of the book details the relationship between arrays and pointers. In C, the name of an array acts as a constant pointer to its first element.
Can we store the address of a pointer? Absolutely. This requires a , denoted by two asterisks ( ** ).

The book discusses dynamic memory allocation using pointers, which allows programmers to allocate memory at runtime. Kanetkar explains the use of functions like malloc() , calloc() , and realloc() to manage dynamic memory allocation.

Allocating memory dynamically via pointers but forgetting to release it using free() . Looking for Yashavant Kanetkar's Explanations?
In C, an array name is actually a pointer to its first element. array[i] is identical to *(array + i) . This equivalence is why array indexing starts at 0. Pointers to Pointers (Double Pointers)
#include int main() int i = 3; int *j; j = &i; printf("Address of i = %u\n", &i); // Target Address printf("Address of i = %u\n", j); // Same Address stored in j printf("Address of j = %u\n", &j); // Pointer's own unique address printf("Value of i = %d\n", i); // Direct value access printf("Value of i = %d\n", *j); // Indirect value access ("value at address j") return 0; Use code with caution.
