#A particular zoo determines the price of admission based on the age of the guest. Guests 2 years of age and less are admitted without charge. Children between 3 and 12 years of
#age cost RM14.00. Seniors aged 65 years and over cost RM18.00. Admission for all other guests is RM23.00. Create a program that begins by reading the ages of all of the guests
#in a group from the user, with one age entered on each line. The user will enter a blank line to indicate that there are no more guests in the group. Then your program should
#display the admission cost for the group with an appropriate message. The cost should be displayed using two decimal places.
