Listing 1 Shows that an array name is pointer

/* array1.c: Uses an array name as a pointer */

/* NOTE: Pointers and ints are 2-bytes in all examples */

#include <stdio.h>

main()
{
    int a[] = {0,1,2,3,4};
    int *p = a;
    
    printf("sizeof a == %d\n",sizeof a);
    printf("sizeof p == %d\n",sizeof p);
    
    printf("p == %p, &a[0] == %p\n",p,&a[0]);
    printf("*p == %d, a[0] == %d\n",*p,a[0]);
    p = a + 2;
    printf("p == %p, &a[2] == %p\n",p,&a[2]);
    printf("*p == %d, a[2] == %d\n",*p,a[2]);
    return 0;
}

/* OUTPUT
