coin problem

[starlight]

How can you make a programe that allows the user to enter the amount of money in cents. and the computer will calculate the smallest number of coins needed to obain this amount of money.

available coin values are:
$0.01
$0.10
$0.25
$1.00
$2.00

thanks in advance

a lot of if statements is wat i would do[/code]

[cool dude]

i love those kinda questions. everyone that starts off in turing has to do stuff like that and they have trouble with it. like "person" said use if statements and make constants which hold the value of something it's a lot easier. the assignment is probably due by now because it's like 15 lines or so, so i want bother posting the code.

k i noticed that u just posted it so i'm guessing your not done. here is the start of the code and the rest is really simple so figure it out

code:

var money : real var sum, sum1, sum2, sum3, sum4 : real var total : real put "please enter amount of money" get money sum:=money/2.00 sum1:=sum/1.00 sum2:=sum1/0.25 sum3:=sum2/0.10 sum4:=sum3/0.01 total := sum + sum1 + sum2 + sum3 +sum4 put "toonies ",sum put "loonies ",sum1 put "quarters ",sum2 put "dimes ",sum3 put "pennies ",sum4

i hope this helps

sorry i messed one thing up so this one is the one thats almost done

code:

var money : real var sum, sum1, sum2, sum3, sum4 : real var total : real put "please enter amount of money" get money sum:=money/2.00 sum1:=money/1.00 sum2:=money/0.25 sum3:=money/0.10 sum4:=money/0.01 total := sum + sum1 + sum2 + sum3 +sum4 put "toonies ",sum put "loonies ",sum1 put "quarters ",sum2 put "dimes ",sum3 put "pennies ",sum4

lol at first i thaught that he ment to use the least number of coins to make a certian ammount, for example $2.37 the least number of coins would be

1 toonie
1 quarter
1 dime and
2 pennies

i'll post the code for this in a seccond just in case that was what you were refering to

yes i am a n00b and u should learn to read because he asked for combinations not wat u gave him

EDIT: i read it again and i realize im the one that needs to read (how ironic)

wat who called u a noob? u r a haker. if your saying i called u a noob their must be some misunderstanding.

plus the second code i gave him works just like he wants it, but he just has to add a few if statements so all of the coins don't show up

sorry im an idiot...i read it again...forgot to see the period....(really pissed off today becasue got 10% on French test)...sorry

[cool dude]

thats okay, happy that was cleared up. sorry for the misunderstanding

Here, what this does is the same thing that somone working a till would do, it works up in each size, starting with the largest, and when that size wont fit anymore it goes with a smaller size of coin, all that it does is adds up with the toonie and then when no more will fit it changes to loonies and counts up, and when they wont fit anymore it counts with quarters, and so on, so i think this is what 'Starlight' was refering to, hope it helps,

code:

var total, current, penny : real var toonie, loonie, quarter, dime, nickel : int put "Enter the total: " .. get total toonie := 0 loop     exit when (toonie + 1) * 2 > total     toonie += 1 end loop current := toonie * 2 loonie := 0 loop     exit when loonie + 1 + current > total     loonie += 1 end loop current += loonie quarter := 0 loop     exit when ((quarter + 1) * .25) + current > total     quarter += 1 end loop current += quarter * .25 dime := 0 loop     exit when ((dime + 1) * .10) + current > total     dime += 1 end loop current += dime * .10 nickel := 0 loop     exit when ((nickel + 1) * .05) + current > total     dime += 1 end loop current += nickel * .05 penny := (total - current) * 100 put toonie, " Toonies" put loonie, " Loonies" put quarter, " Quarters" put dime, " Dimes" put nickel, " Nickels" put penny, " Pennies"

lol i originally forgot to post the code... oopsies

sorry i didn't express this clearly enough. i want a combination of coins that use the least number of coins to make a certian amount . Just as "Token" said in the comment.

[starlight]

thanks. Now I pretty much get how you make the programe. But one more question. what does "+=" mean in turing ?

[Token]

It is an incrementing variable

its the same as putting

total := total + 5

so if the total was before 10 it is now 15

edit: hah beat ya to it Bacchus, look at how close the times were tho

a+=b basically means
a:=a+b , its just short form (you can also do -=), i think theres a tutorial that gives for shortcuts too
