So this is my assignment and when I get the answer after typing yes for bringing vehicle the totals are wrong.


You have been contracted to write a C++ program to calculate the correct fare (using the
fare tariff above), based on an appropriate dialog with the customer. Believe it or not, the
above is actually a somewhat simplified form of the real fare structure! Your assignment
is to develop in C++ a non-graphical (non-GUI) version of the real online fare calculator,
which should ask exactly the same questions, in the same sequence, and produce exactly
the same results.
Example #1
Welcome to Gayathri’s Fare Calculator
Are you driving a vehicle onto the ferry? (y/n): y
Is the driver a senior citizen (65 or over) or disabled? (y/n): y
How many passengers in your vehicle? (excluding the driver)
Adults (age 19 – 64): 1
Senior Citizens (65 or older), or Disabled Persons: 1
Youth (5 -18 years old): 2
Is your vehicle over 7 feet, 6 inches in height? (y/n): y
How long is your vehicle in feet? 17
How many people in your group are traveling with a bicycle? 0
Your total fare is $115.55 Gayathri’s Fare Calculator
Example #2
Welcome to Gayathri’s Fare Calculator
Are you driving a vehicle onto the ferry? (y/n): y
Is the driver a senior citizen (65 or over) or disabled? (y/n): n
How many passengers in your vehicle? (excluding the driver)
Adults (age 19 – 64): 1
Senior Citizens (65 or older), or Disabled Persons: 1
Youth (5 -18 years old): 2
Is your vehicle over 7 feet, 6 inches in height? (y/n): y
How long is your vehicle in feet? 27
How many people in your group are traveling with a bicycle? 0
Your total fare is $171.25
Thank you for using Gayathri’s Fare Calculator
Example #3
Welcome to Gayathri’s Fare Calculator
Are you driving a vehicle onto the ferry? (y/n): n
How many adults (age 19 – 64): in your group? 2
How many senior citizens (65 or older), or disabled persons in your
group? 2
How many youth (5-18) in your group? 3
How many people in your group are traveling with a bicycle? 2
Your total fare is $62.15

A math error, im guessing
naaissus (67)
Line 76:
if (overLength > 14 || overLength < 22)


Line 102:
if (overLength > 22 || overLength < 30)


You want to check if 14 < overLength < 22, i. e. is overLength greater than 14 AND less than 22, right?
So you have to use && (and) logical operator, not ||.
http://www.cplusplus.com/doc/tutorial/operators/

Btw what if e. g. overLength = 14? You might wanna use >= or <= somewhere?

Thank you! All those corrections helped. I do have one last question. I am confused as to what an unnamed variable it? Also did I use any in my code?

BTW thank you for attempting to help. There was not an issue with math just an issue with operators.
