Answer / Kavita Ranjhia
In C programming, pointers are used to store memory addresses. Assigning a pointer to NULL ensures that it does not point to any valid memory location. This is important for preventing undefined behavior or accessing invalid memory. By default, when you declare a pointer but do not initialize it, it may contain garbage values (i.e., random and unpredictable memory addresses).
