can somone edit these

i have a couple of eronious programs and i need somone to help

code:

%flashcards
var a, b, u, x, t : int
x = 0
for t : 1 .. 10
put t
delay (100)
cls
loop
randint (a, 1, 9)
randint (b, 1, 9)
put a, "+", b
get u
if a + b < u then
put "game over, your score is ", x
elsif a + b > u then
put "game over, your score is ", x
else
x := x + 1
exit when a + b < u or a + b > u
end if
end loop
end for
if t = 10 then
put "you ran out of time, your score is", x
else
end if

there is another one aswell

code:

var minute, hour : int
minute := 0
hour := 0
for second : 1 .. 60000
put hour,":",minute,":",second
delay (1000)
cls
if second = 60 then
put minute + 1, ":", second - 60
else
end if
if minute = 60 then
put hour + 1, ":" ,minute - 60
else
end if
end for

if some one can help me i will be great!

you need to ask a question to get any help

sry about that, first post and all . the first one is a flash cards program where they have 1 second to respond with the answer and the other one is just a count up clock. with both of these I ran into some logic problems that i can't work around so, can anyone help me?

guess what i have another one if anyone can curve this line it would be amasing

code:

var x,y:int
x:=maxx div 2
y:=0
for i :1..319
x:=x-1
y:=y+1
drawdot (x,y,12)
delay (20)
end for
if x=0 then
x:=x-1
else
end if

Take a look at all the changes I have made in the last program, and see if you understand them.

Turing:

var x : int
var y, iy : real
x := maxx div 2
y := 0
iy := +0.1
for i : 1 .. 319
x -= 1
y += iy
iy += 0.005
Draw.Dot (x, round (y), 12)
Time.DelaySinceLast (20)
end for

1. iy is how much the y coordinate increases every iteration of the loop, that value increase after it is added to y. This causes the curve.
2. you must round y when you are passing it to Draw.Dot() (drawdot()), because that procedure needs an integer, not a decimal number.
3. x -= 1 is the same thing as x := x - 1
4. use Time.DelaySinceLast() instead of delay(), since it works the same on all computers.
5. Please indent your program, at least use "F2".

As for your other programs, they seem to have logic errors in them, think them through and you should get the right answer. Thing step by step, try to follow what the program does.

Yes, yes, please put replys in the topic which you posted in originally. Hacker Dan wrote: and has a poor subject name. I don't know about a poor subject name though . Well, think about it, for that program you have it so that if second = 60 then... do whatever needed for when the seconds are over a minute. The thing is, what happens when there are 61 seconds? It goes back since second > 60, you need to take that into consideration. Solve that problem on your own, and try to figure out what is wrong with the other program as well. I, or anyone else, won't give you the exact answers, we can only help occasionally.[/quote]

Yo here is ur correct code. hav fun.. %flashcards var a, b, u, x : int x := 0 for t : 1 .. 10 put t delay (100) cls loop randint (a, 1, 9) randint (b, 1, 9) put a, "+", b get u if a + b < u then put "game over, your score is ", x elsif a + b > u then put "game over, your score is ", x else x := x + 1 exit when a + b < u or a + b > u end if end loop end for if b = 10 then put "you ran out of time, your score is", x else end if
