Pattern problem

Question

Input is n=4
Output
₹₹₹ ₹₹₹
₹
&&&&&
₹
₹₹₹ ₹₹₹
Condition n<null

Answer 1

Input is 4 but there are 5 lines of output. What if input was odd number? also other than the '&' the character to print looks unfamiliar, if that was Unicode you should've specifically said so (pretty sure that '₹' character isn't in ASCII table).

The condition `n<null` doesn't sound so clear. null is a special data, comparing a value is not equal to null is possible, but n<null doesn't make sense somehow (cmiiw).
(Edit)
I think null is used for checking pointer validity.
