int main()
{
int a[5] = {1,2,3,4,5};
int *p = a;
p=p+1;;
printf(%d,*(p));
getch();
return 0;
}
After p=p+1, p should point to the next byte after 5, but output in this
case 2. That is p is just travelling inside the array. Is thr any diff b/w
I guess I got that.
(a + 1) increments the pointer to the array(a here) according to the size
of array where as p, being a pointer to an int gets incremented by the size
of int(4 byte in 32 bit compiler) with the statement p = p+1
Correct me if i am wrong.

On Sat,
main()
{
int a[5] = {1,2,3,4,5};
int *ptr = (int*)(a+1);
printf(%d %d , *(a+1), *(ptr-1) );
}
output: 2 5
can someone please exlplain how we are getting 5?

a denotes the address of array
a+1 increments a by size of array and stores in ptr.i.e. ptr points to
end of array
hence ptr-1 will print 5

@Akshata:
Whenever you increase any variable then it increases according to its type.
Here the address of array 'a' is being increased.( a+1 ).
so the address of 'a' will temporarily increased to 20 bytes and then that
is assigned to ptr.
so ptr is now pointing to any value in the memory just
