Write a C++ program that prompts the user to input a string. Your program should convert the message to upper-case letters, substitute digits for certain letters (A->4, B->8, E->3, I->1, O->0, S->5), and the append 10 exclamation marks to the end.

Hint: Store the original message in char array, and then go back through the array, translating and printing characters one by one.
