Write a set of functions that calculate the cost of movie tickets for a family. These functions should use a pass-by-reference variable that accesses the double running_total variable in main().  Using a loop, keep displaying  the ticket prices for each age group: Something like: Model Hall Movie Ticket Box Office Under Age 3 (free) Ages 3-11 ($10.25) Ages 12-54 ($15.50) Age 55 or older ($12) If 4 tickets are purchased (not counting under age 3) then 20% discount Within the loop: Keep asking the user to input the moviegoer age and to enter a zero for the age when they are finished inputting all the family members. Also, within the loop: Keep a running_total that is output to the screenafter each age has been entered. This running_total should be accessed through the functions using apass-by-reference variable. Finally, after the looping is done:  Calculate the total cost, including a 7.5% sales tax, and output it to the screen.
