I need help, please explain :(

Question

var n = 6;
for (int i=1;i<=n;i++)
{
for (int a=1;a<=n;a++)
{
if ((i != 1) && (i != n) && (a != 1) &&(a != n))
{
Console.Write(“ “);
}
else
{
Console.Write(“*”);
}
}
Console.WriteLine();
}

Answer 1

It prints a box, 6 by 6. If i = 1 or 6, or a = 1 or 6. It is the border of the box and it prints a '*'. If a and i are not 1 or 6 it is inside the box and it prints a ' '.

Answer 2

If you change it do this and work with characters instead of strings it works.

var n = 6;
for (int i=1;i<=n;i++)
{
for (int a=1;a<=n;a++)
{
if ((i != 1) && (i != n) && (a != 1) &&(a != n))
{
Console.Write(' ');
}
else
{
Console.Write('*');
}
}
Console.WriteLine();
}
