i need help with this math crap very badly

[asianrandy]

i have problem making this program.
make a program will look like this plz i need help and thank you for doing this for me.


sample invoice is shown below. you must make the numbers line up in columns without using the locate command. Print two decimal place for all currency.
------------------------------------------------------------------------------------------------------------------

Automatic marking machine
cost: $55.99


customer name : nameless
business name : nameless

number of items ordered: 4

total cost of items : 223.80
postage and handling: 30.00

subtotal: 253.80

5% GST: 15.23
8% PST: 20.30

fianl total: 289.33

No-one here does work for you, you need to show your work and we can help you. Requesting someone to do so is agains't the rules.

[OneOffDriveByPoster]

Does Turing have a "log" function? It could help.

[[Gandalf]]

Turing only has a ln(n) function, however I doubt any of that would help as the poster seems to have trouble with "this math crap".

Be more specific in your questions if you want help.

[Tony]

well the only "math crap" that's involved in printing an invoice is addition and sometimes multiplication, but only if you want to figure out what the tax is.

(I'm not sure how log is applicable)

@asianrandy -- here's an example that will perhaps help you figure out how to do addition.

Turing:

var item1 : real := 55.99 var item2 : real := 5.99 put "The total of 2 items is: ", item1 + item2

[asianrandy]

% This program will print out invoices to send to people with their orders
locate (1, 25)
put "AUTOMATIC MARKING MACHINE"

var name : string
put "Customer Name: "
locate (2, 15)
get name

var total : real := 0
var product : int
loop
put "number of items ordered (1=Computer, 2=computer2, 3=computer3, 4=computer4, 5=postage and handling, 6=quit): " ..
get product
if product = 1 then
total := total + 55.95
elsif product = 2 then
total := total + 111.90
elsif product = 3 then
total := total + 167.85
elsif product = 4 then
total := total + 223.8
elsif product = 5 then
total := total + 30.00
elsif product = 6 then
exit
end if

% The phrase "total : 0 :2" outputs total to two decimal places
put "The running total is $", total : 0 : 2
end loop
put "Final total = $", total : 0 : 2

this is what i got but l'm close to it

[asianrandy]

can you give me some tips on turing on addition

[Insectoid]

Use another counter to get number of items, then, at the end, cls and print everything the way you want.

[asianrandy]

i need help where to put the 5%gst and 8%pst and what the code for it

% This program will print out invoices to send to people with their orders
locate (1, 25)
put "AUTOMATIC MARKING MACHINE"

var name : string
put "Customer Name: "
locate (2, 15)
get name


put "Total of items ordered " ..
var number : string
get number
var total : real := 0
var product : int
loop
put "Total Cost of items: " ..
get product
if product = 1 then
total := total + 55.95
elsif product = 2 then
total := total + 111.90
elsif product = 3 then
total := total + 167.85
elsif product = 4 then
total := total + 223.8
elsif product = 5 then
total := total + 30.00
elsif product = 6 then
exit
end if


% The phrase "total : 0 :2" outputs total to two decimal places
put "Total Cost of items: $", total : 0 : 2
end loop
put "6% GST:"

put "Final total = $", total : 0 :

[asianrandy]

i dont no how to fix the problem

[Euphoracle]

Multiplication in turing is done using an multiplication operator in the form of an asterisk:

Turing:

put "3 x 5 = ", (3 * 5) : 0

Remember, however, that expressing a percentage as a decimal requires you to first divide it by 100. The reasoning for this is the fact that a decimal totals up to 1 (0.5 + 0.5 = 1), whereas percentages total up to 100 (50% + 50% = 100%).

Knowing this, you should be able to calculate 6% GST of the total cost of the items.

[asianrandy]

Automatic marking machine
cost: $55.99


customer name : nameless
business name : nameless

number of items ordered: 4

total cost of items : 223.80
postage and handling: 30.00

subtotal: 253.80

5% GST: 15.23
8% PST: 20.30

finall total: 289.33

so far i got is this



var name : string
put "Customer Name: "
locate (1, 15)
get name

var items : string
put "Number of items ordered: "
get items

var total : real := 0
var product : int
loop

get product
if product = 1 then
total := total + 55.95
elsif product = 2 then
total := total + 111.90
elsif product = 3 then
total := total + 167.85
elsif product = 4 then
total := total + 223.8
elsif product = 5 then
total := total + 30.00
elsif product = 6 then
exit
end if


% The phrase "total : 0 :2" outputs total to two decimal places
put "Total Cost of items: $", total : 0 : 2

end loop
put "Final total = $", total : 0 : 2

[size=24]and i ended up [/size]

customer name: myname
number of items ordered: 4

l'm right to get any number i want and get whatever i want too add $ 30.00 then add the subtotal
then calculate the subtotal to get the gst and pst and get the final total.
I have no idea what to do. The Introduction to programming book doesn't tell you what l'm doing.
it quite confusing.

[Insectoid]

The introduction to programing (in Turing??) book is utter crap. I assume you're talking about the holtsoft one?

First, you need to use code tags. they work like this:

code:

[code]paste code here[/code]

. This makes it easier for us to read and then find the problem.

Second, I am afraid that if this simple program is this complicated for you, you will not get far in the field. I'm not trying to be mean or anything, but it's the truth.

On to helping! Okay, you are asking the user for the number of items they are ordering. This is bad. Instead, every time they add to the order, add one to 'items' (which has to be an int, you've declared it as a string)

so this:

code:

get product if product = 1 then     total := total + 55.95 end if

becomes this:

code:

get product if product = 1 then     total += 59.95 %a quick way of saying foo := foo + 1)     items += 1 end if

It only takes one extra line and streamlines the user's experience.

[S_Grimm]

insectoid is right. You need a pile of "if" statements (One for each product) and then put them in his code (so instead of "if product = 1 then", you need "if product = 2", "if product = 3", etc..)

[SNIPERDUDE]

Or a Case Statement.
