Is Null Or 0 C. A common solution that catches many errors is to set all pointers that don't point to anything as null (or, in correct c++, 0), and checking for that before. It is not the same as the character ‘0’ which has an ascii value of 48. #include <stdio.h> int main (void) {int * p_some_variable = null; The null pointer is the pointer that does not point to any location but null. The null character in c is a special character with an ascii value of 0 (zero). The c standard defines that 0 is typecast to (void *) is both a null pointer and a null pointer constant. The null macro may be defined by the implementation as a naked 0, or a cast expression. You can check if a pointer is a null pointer by comparing it to null: The null pointer constant is always 0. The null character in c is used to denote. The macro null is provided in. Perhaps the element that causes the most confusion is the \0 escape character. That’s the null character, which is used in c to terminate a string of text. “an integer constant expression with the value 0, or such an expression cast to type void *,.
