Kanetkar explains the deep relationship between these two, clarifying how array names function as constant pointers and how to perform pointer arithmetic.

A NULL pointer points to nothing (address 0 ). Always check if your pointer is valid before attempting to extract its value using the * operator. int *ptr = NULL; if (ptr != NULL) { printf("%d", *ptr); } Use code with caution. Conclusion: Learning Beyond the PDF

Never declare a pointer and use it without assigning an address. It will point to a random location in memory. Always initialize pointers to NULL if they aren't immediately pointing to a valid variable.

Dereferencing a pointer means accessing the value stored at the address contained in the pointer. *ptr gives you the value of age (25). 4. Pointer Arithmetic
