#include <stdio.h>
 
int main(void)
{
    int array[3] = {0};
    int *p1 = &array[0], *p2 = &array[1];

    printf("p1 = %p\n", (void*) p1);
    printf("array = %p\n", (void*) array);
    printf("p2 = %p\n", (void*) p2);
    printf("&array[1] = %p\n", (void*) &array[1]);
    
    *p1 = 18;
    *p2 = 99;
    
    for (int i = 0; i < 3; i++)
        printf("%3d", array[i]);
     
    return 0;
}
   
    
/*

p1 = 000000000022FE20
array = 000000000022FE20
p2 = 000000000022FE24
&array[1] = 000000000022FE24
