Question

Describe the pseudocode for the following problem:

Design a program to calculate the price of a road trip. The different modules or methods needed would be calculating the cost of gas for the trip, calculating the lodging for the trip, calculating the cost of food for the trip, calculating the cost of admission to any sightseeing for the trip, etc. Try to design the pseudocode so that you are asking each module to return a value and the main method just adds up the costs based on what is returned from each method. The main method might need to ask the user how many days they are traveling and where they are going and then pass this information into the modules that need it.

Answer 1

1. float gascost(int days)
2. {
3. read gas_per_day;
4. return days *gas_per_day;
5. }
6. float lodging(int days)
7. {
8. read lodge_per_day;
9. return days *lodge_per_day;
10. }
11. float food(int days)
12. {
13. read cost_break_fast;
14. read cost_lunch;
15. read cost_dinner;
16. read cost_snacks;
17. total =(cost_break_fast+read cost_lunch+read cost_lunch+read cost_snacks)*days;
18. return total;
19. }
20. float miscellaneous(int days)
21. {
22. total=0;
23. for i=1 to days:
24. {
25. read expense;
26. total=total+expense;
27. }
28. return total;
29. }
30. void main()
31. {
32. read no_days;
33. total_cost=gascost(no_days)+lodging(no_days)+food(no_days)+miscellaneous(no_days);
34. display(total_cost);
35. }
