(8) Implement the ReplaceExclamation() function. ReplaceExclamation() has a string parameter and updates the string by replacing each T character in the string with a character. ReplaceExclamation() DOES NOT output the string. Call ReplaceExclamation() in the ExecuteMenu() function, and then output the edited string. Ex. Edited text: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue.
