Worried newbie

I have just recently started college and with it started using vb6 for the first time, recently i was given a task to do but because i have little or no experience with this im really worried because i have become so worried about the problem that my brain wont allow me to think about it without panicing....

What shape will be displayed by the following vb program for any value of n>1?
for i = 1 to n
for j = 1 to i
print "+";
next j
print
next i

Im sure this is very easy but i sit here pen in hand cunfused and realy worried

Im not looking for the answer but an understandable explanaition and an example of my problem so i can do it myself

Thankyou for any help

why don't you try to compile it and run it?

Output for n=5

Im not aloud to do that, i have to do it on paper.

OpenLoop

then run it on the paper. Pick a value for n, say n = 3 and go thru the loop one iteration at a time and record the output everytime you encounter a "print" statement.

I have had a go and come out with three different out comes.

First is
1
12
123
1234
12345

second is
1
23
345
4567
56789

Third is
1
23
345
4567
56789

They were n=5..... now in really confused but i think one is correct?

OpenLoop

If you where printing j the first one will be correct for n=5. But look at the code closely, what are you printing? You're printing "+" for every iteration of the nested loop(the one with j) and a new line for every iteration of the i loop.
Follow the same logic you did in your first try but take what i said in consideration.

Ok so im trying to think, if n = 10 it would look like this
+
++
+++
++++
+++++
++++++
+++++++
++++++++
+++++++++
++++++++++

I know this must seem so easy to some people but it can be very confusing to a first time user so thanx a lot for all the help

OpenLoop

Yes, you got it. Now try to understand it very well, this is a good exercise on loops.

Let me just confirm this if n = 12 and print is "*": then it should look like this
