Assign NULL pointer
Description
NULL is a constant defined in the standard
library and is the equivalent of zero for a pointer.
NULL is guaranteed not to point to
any location in memory.
Example
#include <stdio.h>
//from w w w.j a va 2 s. c o m
int main(void)
{
int number = 0;
int *pointer = NULL;
number = 10;
printf("\nnumber's address: %p", &number); /* Output the address */
printf("\nnumber's value: %d\n\n", number); /* Output the value */
return 0;
}
The code above generates the following result.
