Explaining Code Reading Problem: for (int i=0; i<=9; i++)

[chmate]

Hi!

for (int i=0; i<=9; i++)
{
   for (int j=0; j<i; j++)
       cout << " ";
   for (int j=i; j<=9; j++)
        cout << "*"
   cout << endl;
}

Can anyone explain me what these lines are doing?

Thank you!

what do you think the are doing?
Do you know how to trace through code like that?
...write it all out on bpaper.

If you don't know what a for loop does then i can't help ya.
the "cout<<endl" is just a new line.

EDIT: oh yeah you also hav ean error in your j-for loops

I don't know. It seems like it's printing 9 lines, each line having an increasing number of spaces and decreasing number of stars. But i can't figure out what something like that can possibly look like.

It does this:
**********
*********
********
*******
******
*****
****
***
**
*
Press any key to continue
When you don't try to redfine j in:
for (int j=i; j<=9; j++).. (I used x)
and correct the syntax error by adding a semi-colon to:
cout << "*"
Sorry for butting in...

What it will look like depends on the font you use.
But, most things like this are ment for a fixed spacing font.
So take some graph paper and plot it out.
