Answer 1

It's supposed to create a n by n box. The box is represented by a matrix.

"i" is the row number. "j" the column number.

First row is line (all stars). Thus the "i == 1" condition. No matter which column, there will be a star.

The same goes for the last row which is the "i == n" condition.

For any other row, only the beginning and end have stars. Expressed by conditions "j == 1" and "j == n".

The if statement will print star if any of the conditions are true. Expressed by the logical or statements "||".
