Consider the following C program:
#include <stdio.h>
int main () {
int arr [] = {1,2,3,4,5,6,7,8,9,0,1,2,5}, *ip = arr+4;
printf ("%d\n", ip[1]);
return 0;
}
The number that will be displayed on execution of the program is _____.

Question 1 Explanation:
We know that arr is a pointer to arr[ ] & hence arr+4 is pointer to 4th index of array (starting from 0 to 4).
Now *ip is a pointer of int type pointing to memory location 108, which is part of arr.
Hence, when we will print ip[1] it will be equivalent to *(ip+1).
Address of ip will be incremented by 1 & value inside 110 will be printed.
