What Is The Difference Between An Uninitialized Pointer And A Null Pointer at Taj Joanne blog

What Is The Difference Between An Uninitialized Pointer And A Null Pointer. A null pointer has a specific value and a specific representation. It doesn't point to an object, but it is still a single, predictable, known value, reserved. If a null pointer constant is converted to a pointer type, the resulting pointer, called a null pointer, is guaranteed to compare unequal to a pointer to any object or function. Pointers declared in the program. What is null pointer in c? A null pointer in c is a special type of pointer which points to nowhere i.e. Strictly, an uninitialised pointer has an indeterminate value. An uninitialized pointer is a pointer which points unknown memory location while null pointer is pointer which points a null value or base address. Using an uninitialized pointer is undefined behavior, but dereferencing a null pointer is also undefined behavior (both could lead to a. Pointing to nowhere, and being uninitialised, are two different concepts. “an integer constant expression with the value 0, or such an expression cast to type void *, is called a null pointer constant. If a null pointer constant is converted to a pointer type, the resulting.
