C Is Null Always Zero at Alyssa Kellett blog

C Is Null Always Zero. If a null pointer constant is converted to a pointer type, the resulting pointer, called a null. } } in practice, null is a constant equivalent to 0, or \0. “an integer constant expression with the value 0, or such an expression cast to type void *, is called a null pointer constant. The null pointer constant is always 0. If (p_some_variable == null) { printf(equal); The null macro may be defined by the implementation as a naked 0, or a cast expression like (void *) 0, or. Using the constant 0 (or any constant expression evaluating to 0) anyplace where null would be used is safe, as 0 is a. This is why you can set a string to null using: The macro null is provided. That’s the null character, which is used in c to terminate a. The null pointer is the pointer that does not point to any location but null. #include <stdio.h> int main(void) { int * p_some_variable = null; The c standard defines that 0 is typecast to (void *) is both a null pointer and a null pointer constant. You can check if a pointer is a null pointer by comparing it to null: Perhaps the element that causes the most confusion is the \0 escape character.
