Question

I am having trouble with my assignment and getting compile errors on the following code. The instructions are in the initial comments.

/*
Chapter 5, Exercise 2
-Write a class "Plumbers" that handles emergency plumbing calls.
-The company handles natural floods and burst pipes.
-If the customer selects a flood, the program must prompt the user to determine the amount of
damage for pricing.

-Flood charging is based on the numbers of damaged rooms.
1 room costs $300.00, 2 rooms cost $500.00, and 3 or more rooms cost $750.00.

-Pipe bursting is based on the number of pipes: 1 pipe costs $50.00, 2 pipes cost $70.00,
and 3 or more pipes cost $100.00.

-The Plumber class should contain a nested class to handle billing charges.
Use And, Or, and Not in the if statements to obtain the customers' inputs.

Answer 1

You have done simple mistakes like variable names using incorrectly, else without if.

Please check the lines in the below picture to get out of compile-time errors:

1. Line 37
2. Line 57
3. Line 59
4. Line 63

I have marked them bold.
