want to check whether d operand is even number

Question

a = 42
b = 8
c = 20
d = 4
if a > 7 && b < 11 && c == 20 && d????
puts "Statement is correct."
end

Answer 1

you can use the even? method:
'd.even?' returns true if d is even else false.

or the traditional way 'd%2==0' ,
d is even if remainder of its division by two is null.
