GATE 2013 Comprehensive Information Page @ http://www.codeblocks.info/2012/08/gate-2013.html

What does the following fragment of C program print?

  char c[] = "GATE2011";
  char *p = c;
  printf("%s", p + p[3] - p[1]);

(A) GATE2011
(B) E2011
(C) 2011
(D) 011

Answer: (C) 2011

Explanation:
p[3] = A (Ascii = 65)
p[1] = E (Ascii = 69)
p[3] - p[1] = 4
p + p[3] - p[1] = p + 4


printf starts printing from the p + 4 till the end giving 2011
