looping possibility?

[moneywin]

can anyone tell me why my total cant be outputted in this program? THANKS .
and
is it possible to have a if statemnet inside of a if statement in another if statement ?


My Problem :

var destination, answer, qualityt, qualitytt : string
var total : int
total := 0

put " These are the choices"
1. Hawaii
get destaination

if destination = 1 then
put "would you like to play by airplane or train?"
get answer
if answer = train then
put " First Class or Economy"
get qualityt
if answer = "First Class" then
total := total+600
elsif answer = "Economy" then
total := total + 400
end if

elsif answer = "airplane" then
put "First Class or Economy"
end if
get qualitytt
if answer = "First Class "then
total := total +300
end if
elsif answer = "Economy" then
total := total +200
end if

put "you have deceided to go to", destination, " the price of your travel is", total

The answer is Yes, any statement within itself would be referred to as Nested.

A Nested If structure is composed of multiple if statements inside of each other

Note: I HIGHLY advise pasting your code into One Turing window, and My code into another, and Compare!

Turing:

var destination, answer, qualityt : string var total : int := 0 put "Where would you Like to Travel to?      ", "Type '1' for Hawaii." get destination put skip if destination = '1' then     put "Would you like to Travel by Airplane, or Train?   " ..     get answer     if answer = "Train" or answer = "train" then         put skip         put "Would you like to travel in First Class, or Economy?  "         get qualityt : *         if qualityt = "First Class" or qualityt = "first class" then             total += 600         elsif qualityt = "Economy" or qualityt = "economy" then             total += 400         end if     elsif answer = "Airplane" or answer = "airplane" then         put skip         put "Would you Fly in First Class, or Economy?  "         get qualityt : *         if qualityt = "First Class" or qualityt = "first class" then             total += 300         elsif qualityt = "Economy" or qualityt = "economy" then             total += 200         end if     end if end if put skip put "You have decided to go to ", destination, ", the price of your travel is: $", total

[Aange10]

I have decided to go to 1 the price of my travel is: $600

(: I always wanted to visit 1

[moneywin]

I wanna thank you first of all, and secondo fl all what does
get qualityt: * represent?

[moneywin]

Also do yo u knwo how come?


total +=300

^what does it mean?

i thought it was

total := total +300
^ but when i tried this it doesnt work :/

im sorry for these questions, i just wana learn from my mistake.

and thanks

when you need the user to enter a string, It returns all the characters, but if they're entering Two or more words containing a space, it only returns the word up until the space.

Turing:

get word : *

what the colon + asterisk does is ensures that the computer receives everything the user types, until the Enter key is hit. I noticed that when I fixed your program, only Economy worked, because when you would type "First Class", the computer gets the word "First", but nothing after because of the space. This was preventing adding the total.


As for

Turing:

total += 300

That is the exact same as :

Turing:

total := total + 300

The "+=" combination means to increment whatever value on the right, to whatever value on the left.

if i wish to do more than one place , why doesnt it work, i used your format as an example: but im really curous to why it cnat due more than one desintation, like i tried running it , and the places always end up being $0
For examples ; i typed in " 2 " and it would skip all the process, and its hte same problem when i type in 3,4,5,6.

and with great gratidue , for all your help. You have taught me how to do turing, i have a much better understanding now. Thanks.

[Aange10]

Well, your problem is you can't just stick end if at the bottom of the program and call it good.

You have to end the ifs when their condition stops applying, not at the bottom.


All of you're destinations work, except for the fact that you never end the conditions determining which place you chose to go.

A quick fix:

Turing:

var destination, answer, qualityt : string var total, people : int total := 0 put "How many people are going" get people put "Where would you Like to Travel to? " put "Type '1' for Hawaii." put "Type '2' for California" put "Type '3' for Hollywood" put "Type '4' for South Pole" put "Type '5' for North Pole" put "Type '6' for Artic" get destination put skip if destination = '1' then     put "Would you like to Travel by Airplane, or Train?

Do you see what you did wrong?

[Beastinonyou]

I can't stand to look at all that unnecessary coding.

I advise you take a look at this:

Turing:

var answer, qualityt : string var people, total, destination : int := 0 var trainFC : array 1 .. 6 of int := init (600, 780, 900, 1200, 780, 900) var trainE : array 1 .. 6 of int := init (400, 450, 600, 1000, 600, 400) var airplaneFC : array 1 .. 6 of int := init (300, 500, 800, 1300, 1000, 500) var airplaneE : array 1 .. 6 of int := init (200, 600, 1000, 1200, 800, 600) procedure allInOne (destination_ : int, answer_, qualityt_ : string)     if qualityt_ = "First Class" or qualityt_ = "first class" then         if answer_ = "Airplane" or answer_ = "airplane" then             total += airplaneFC (destination_)         elsif answer_ = "Train" or answer_ = "train" then             total += trainFC (destination_)         end if     elsif qualityt_ = "Economy" or qualityt_ = "economy" then         if answer_ = "Airplane" or answer_ = "airplane" then             total += airplaneE (destination_)         elsif answer_ = "Train" or answer_ = "train" then             total += trainE (destination_)         end if     end if end allInOne put "How many people are coming? " .. get people put "" put "Where would you Like to Travel to? " put "Type '1' for Hawaii." put "Type '2' for California" put "Type '3' for Hollywood" put "Type '4' for South Pole" put "Type '5' for North Pole" put "Type '6' for Artic" put "Where would you like to go? " .. get destination put "" put "What would you like to travel by? " .. get answer put "" put "First Class or Economy? " .. get qualityt : * put "" allInOne (destination, answer, qualityt) put "Your Total Estimate is: $", total * people

OR:

Turing:

var answer, qualityt : string var people, total, destination : int := 0 var trainFC : array 1 .. 6 of int := init (600, 780, 900, 1200, 780, 900) var trainE : array 1 .. 6 of int := init (400, 450, 600, 1000, 600, 400) var airplaneFC : array 1 .. 6 of int := init (300, 500, 800, 1300, 1000, 500) var airplaneE : array 1 .. 6 of int := init (200, 600, 1000, 1200, 800, 600) function allInOne (destination_ : int, answer_, qualityt_ : string) : int     if qualityt_ = "First Class" or qualityt_ = "first class" then         if answer_ = "Airplane" or answer_ = "airplane" then             result airplaneFC (destination_)         elsif answer_ = "Train" or answer_ = "train" then             result trainFC (destination_)         end if     elsif qualityt_ = "Economy" or qualityt_ = "economy" then         if answer_ = "Airplane" or answer_ = "airplane" then             result airplaneE (destination_)         elsif answer_ = "Train" or answer_ = "train" then             result trainE (destination_)         end if     end if end allInOne put "How many people are coming?

Well, everybody goes through that..

When somebody on the forums solves your problem, you look at it and go, "damn, why didn't I think of that", or "Wow, I didn't realize that could be done in that way." Now, they can learn to work with them, and they'll get better with them.

The more practice you get with a concept, the more familiar you are with using it. When you started your first month in programming in Turing, did you go over Procedures and Functions? Not likely, most teachers are just teaching you repetitive structures, and graphics.


Realistically, It was more like Constructive Criticism.

[Zren]

Turing:

if answer_ = "Airplane" or answer_ = "airplane" then

Ew.

Turing:

put Str.Lower("AbC") = Str.Lower("aBc") if Str.Lower(a) = Str.Lower(b) then

Basically you compare strings insensitive to their case.

Could've done that, but procedures / functions would have been enough of a change in his program.

Str.Lower and Str.Upper is mainly just for convenience

I started my first month two months ago. Concept takes a while to learn. Problem-solving takes a while to figure out. Syntax is given for a language. I learned procedures the same day I learned put (Functions confused me because of the typespecs).

It should not be hard to learn (especially such easy) syntax. Turing Walkthrough has 95% of everything in it. Google is free for everybody with internet to use.
