Answer 1

See your pattern on rows = 5

First row has 1 *
Second row has 2 *
Third row has 3 *
Fifth row has 5 *

So i is for rows
And j is to print number of stars

In your code there is little change.

There should be i < r and j <= i

* //When i = 0, j should be j <= 0;
** //When i = 1, j should be j <= 1;
*** // When i = 2, j should be j <= 2;
****
***** //When i = 4; j should be j <= 4;

If you write j <= row instead of j <= i then on every new line same amount of * will be print

Means when row = 5

Then pattern would be like this: You can try

*****
*****
*****
*****
*****

Each row will have 5 *

But when you do j <= i then number of * will be print on the basis of i

So
when i = 0 then *
When i = 1 then **
When i = 2 then ***
When i = 3 then ****
When i = 4 then *****

Answer 2

Where is your code?

There might be many situations but in which situation you are asking?

Answer 3

Additionally your signature for:

int starpattern(int r)

is expecting an int returned to the call. You have no return value. For what you are trying to do in the function you will not need one. Simply change it to:

void starpattern(int r)

and you will not get the error any more.
