NO... this will cause problems, here is why
int* pi; // declare a pointer to an int
pi = new int[5]; // pi points to an array of 5 ints
// ok here lets say that pi's memory address is 123
pi++; // pointer arithmetic, pi now points to 124
delete[] pi;
// this call to delete will delete starting at 124 and NOT 123

Well, the consequence for this "stub" is that your programm will crash. Simply said. 
As Matt already said, delete will begin deleting at (pseudo) address 124 and it tries to delete 5 "ints".
This causes a memory error, which leads to the crash.
