Using the & and * operators
#include <stdio.h>
int main()
{
int a; /* a is an integer */
int *aPtr; /* aPtr is a pointer to an integer */
a = 7;
aPtr = &a; /* aPtr set to address of a */
printf( "The address of a is %p"
"\nThe value of aPtr is %p", &a, aPtr );
printf( "\n\nThe value of a is %d"
"\nThe value of *aPtr is %d", a, *aPtr );
printf( "\n\nShowing that * and & are complements of "
"each other\n&*aPtr = %p"
"\n*&aPtr = %p\n", &*aPtr, *&aPtr );
return 0;
}The address of a is 9a37c The value of aPtr is 9a37c The value of a is 7 The value of *aPtr is 7 Showing that * and & are complements of each other &*aPtr = 9a37c *&aPtr = 9a37c
