Consider the following code:
#include <iostream>
int main()
{
int a[5] = {0, 5, 2, 3, 4};
int *p = a;
++*++p;
std::cout << a[1] << std::endl;
return 0;
}
/* Output:
6
*/Explanation:
The first ++ will increase the value on its right side (*++p).
According to the rules of precedence, ++p will be executed before the pointer is dereferenced, so the pointer (which was pointing to the first element (element 0) of the array) now points to the second element (element 1) of the array, then the pointer is dereferenced.
The value (that we got by dereferencing that pointer) will now be increased by one.

He couldn't help it, first he hijacked a thread, then a moderator was informed to split this into a new thread, and the thread's title was decided by a moderator.
