arrays

[Diroga]

can i goto a point in an array and change it's vaule? if so how? example

for i = 1 to 6
num(i)=i
next

i want to change num(3)=3 to num(3)=4

You just answered your own question...

to change num(3) to 4, just put the line

num(3) = 4

where you want it. If you want them all to be one bigger, then

for i = 1 to 6
num(i) = i + 1
next i

Now, go rtfm.

I suggest "RTFM" be put in the banned-word list, and the auto-replacement text for it should be "RTFM [http://www.qbasicnews.com/manual]" or wherever it's located... cuz how do newbies know what rtfm means?

[Diroga]

well tfm i have did say i could do that num(3)=4

Code:

FOR i = 1 TO 6
num(i) = i
NEXT

FOR i = 1 TO 6
num(4) = 3
PRINT num(i)
NEXT

ok i am pround to say i know very little about qb but i'm learning. and learings half the battle.

And it was right.

What is this?

Code:

FOR i = 1 TO 6
num(4) = 3
PRINT num(i)
NEXT

You don't need to make num(4) = 3 six times over. It can remember it by itself, it's a computer

[Diroga]

it's an example of replacing a value. the out put is 1 2 3 3 5 6 insted of 1 2 3 4 5.

[oracle]

Code:

FOR i = 1 TO 6
  num(i) = i)
NEXT i
num(4) = 3
FOR i = 1 to 6
  PRINT num(i)
NEXT i

Much more efficient than doing the same thing 6 times...

[Diroga]

i get what your saying now. the num(4)=3 should be insde the for...next. that shouldnt slow it down much would it?

Having it inside the loop slows it down a little. What he's saying is it's better to have to outside the loop.
