Write a class Amount which stores sums of money given in pounds and pence. Your con- structor should take two ints, for pounds and pence seperately. The class should also provide methods to add and withdraw money, again in pounds and pence, and a toString method that returns the balance in the format ?£X.XX?, ?£XX.XX?, ?£XXX.XX?, and so on, as appropriate. If a withdrawal would make the balance less than zero, your class should print an error message to the screen and ignore the withdrawal.
