C programming

Question

#include<stdio.h>   

int main()

{

  int a[] = {1, 2, 3, 4, 5, 6};

  int *ptr = (int*)(&a+1);

  printf("%d ", *(ptr-1) );

  return 0;

}

Give the output with explanation.

Comments

output should be 6

---

yes, when you add 1 to &a, it is displaced by a factor of array size. So,&a + 1 points to next memory location after the array and since ptr is an integer pointer (ptr - 1) points to memory location containing 6
