Turing Program

[slider203]

Hi I have to make a proram for my compsci class and I keep running into problems could anyone please point me in the right direction

ok this is the problem
Write a program which will display a conversion table from miles to kilometers (1 mile = 1.6 km) Design the program so that the values for miles increases by 5. The table will start with 5 and end with 100 miles.

Your output will look like this
Miles Kilometers
5 8.0
10 16.0
15 24.0
... ....
... ...
.. ....
100 160

This is my code so far:

for count : 5..10
var miles:= count ** 5
var kilometers: real
kilometers:= miles * 5.6
put "Miles ", miles, " Kilometers ", kilometers
end for

If anyone could please teach me what to do I dont want you to just write the code for me, I just need help in making MY code work so if someone could please point out the error in my code that would be much appreciated.

Thanks for any help

For allows you to increment by values other than one, I think it looks like:

for count: 1..10 by 5
%Do stuff
end for

[edit] I think the only problem with your program above is that you're using exponents (**) instead of multiplication (*)

Try and think of it functionally (or graphically). The variable miles would be the dependant variable. So if you did what DtY said, you could eliminate count and call it miles instead (miles would increase by 5 till it reaches ____).

for miles : 5 .. ____

Then you'd convert miles to kilometers. I think your a little confused with this part because of this:

"kilometers:= miles * 5.6 "

Right now if miles = 5, kilometers would equal 28. Not what we're looking for. So how does 1 convert to 1.6? And 5 to 8?

You are close, I think you are over complicating the problem.

You have it right that you need to use a counted loop but you may want to try from 5 to 100 by 5 instead of 5 to 10 and then doing extra math.

Inside that loop you really don't need to use any variables all you need to do is output this (and note this is in sudocode because I am not giving you the complete answer).
Output: "Miles " [count] " KM " [count x 1.6]

Thats it. It should be exactly 3 lines when done.

If you were to use that then it would only output 1 and 6. It should be 5 to 100 by 5 to output 5, 10, 15, 20, 25...95, 100.

Just pointing that out.
