Question
Countrywide Tours conducts
sightseeing trips for groups from its
home base in Iowa. Create an
application that continuously
accepts tour data, including a
three-digit tour number; the
numeric month, day, and year
values representing the tour start
date; the number of travelers taking
the tour; and a numeric code that
represents the destination. As data is
entered for each tour, verify that the
month, day, year, and destination code
are valid; if any of these is not valid, continue
to prompt the user until valid data is
entered. The valid destination codes are
shown in Table 6-6.
pseudocode for: chapter 6 in programming,design and logic n0 10: Design the logic for an application that
outputs each tour number, validated
start date, destination code, destination
name, number of travelers, gross total
price for the tour, and price for the tour after discount. The gross total price is
the tour price per guest times the number of travelers. The final price includes a
discount for each person in larger tour groups, based on Table 6-7.

Price per
Person ($)
1 Chicago 300.00
2 Boston 480.00
3 Miami 1050.00
4 San Francisco 1300.00
