Question 6 (25 pts.). Write a program that takes as input any change expressed in cents. It should then compute the number of half-dollars, quarters, dimes, nickels, and pennies to be returned, returning as many half-dollars as possible, then quarters, dimes, nickels, and pennies, in that order. For example, 483 cents should be returned as 9 half-dollars, 1 quarter, 1 nickel, and 3 pennies. Input: Change in cents. Output: Equivalent change in half-dollars, quarters, dimes, nickels, and pennies. Question 7 (25 pts.). Write a C++ program that prompts the user to input the elapsed time for an event in seconds. The program then outputs the elapsed time in hours, minutes, and seconds. (For example, if the elapsed time is 9,630 seconds, then the output is 2:40:30 )
