#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
