The prototypical Internet newbie is a fellow named BIFF, who has a unique way of writing messages. Here's a typical BIFF Communique: H3Y DUD3, C 15 RILLY COOL !!!!!!!!!!! Write a "BIFF filter" that reads a message entered by the user and translates it into BIFF - speak: Enter message: Hey dude, C is rilly cool In BIFF - speak: H3Y DUD3, C 15 RILLY COOL !!!!!!! Your program should convert the message to upper - case letters, substitute digits for certain letters (A rightarrow 4, B rightarrow 8, E rightarrow 3, I rightarrow 1, O rightarrow 0, S rightarrow 5), and then append 10 or so exclamation marks
