I was solving last years GATE question paper where i am stuck with this question
What does the following fragment of C-program print?
char c[]="GATE2011";
char *p =c;
printf ("%s", p+p[3]-p[1]);
The answer is ‘2011’
I am aware that in c, array variables are pointer to first address of the array. My logical answer was ‘E2011’, but the output is 2011
Can someone explain the pointer mathematics involved in this?
p[3] = A
p[1] = E
E – A = 4
hence p + 4 = address of 2
hence it prints 2011
