SPOJ.com - Problem ARR

ARR - ARRAY(EASY)

no tags

Replace "?" with a integer so that output is 4.

  int main() {
    int arr[7];
    int b,c,d,a;
    a=4;
    printf("%d",arr[?]);
    return 0;
  }

No input.

Write only one integer as the answer. And submit as TEXT.

Note: Don't submit whole program and assume no optimization by compiler.



	Simes: 2025-02-03 21:08:22 Is this problem supposed to illustrate the memory allocation and lack of array bound checking in C and C++ compilers?
	nadstratosfer: 2018-05-26 17:29:55 Useless problem. Last AC submission 4.5 years ago -- the number I get with every compiler gets WA here. Please delete this.
	vivek yadav: 2011-01-25 16:53:41 at my my comiler it give correct output but on spoj it give wrong answer. why???
	যোবায়ের: 2010-12-17 14:12:26 I use many different local and online compiler and could not manage it to print 4 with arr[x] where, x is the integer I got AC with, so, its all about "how compiler behaves" or more specifically "how compiler allocates memory" :p
	.::Manish Kumar::.: 2010-11-09 05:24:17 Moved to tutorial. I did not remove it, because it would draw attention towards how compiler behaves. [Simes]: WHICH compiler? Last edit: 2025-02-03 21:08:47
	Varun Jalan: 2010-11-09 05:24:17 Move it to the tutorial section or even better remove it altogether. Firstly it does not test any particular feature of the C language, and is not standard. Also, some compilers would optimise and not allocate b,c,d, while some would.
	Shaka Shadows: 2010-11-09 05:24:17 The problem has been designed considering just a particular compiler. Mine, which is gcc/g++ 4.4 never outputs 4 with the output value. So, a small hint: think as a compiler and forget about yours :)
