Wrong number of arguments

---

• We have a function that expect two integers. Can we instead pass an array of two integers?
• Normally no, but there are at least 3 solutions

examples/functions/pass_array_instead_of_individual_values.cr

def f(x, y)
  return x + y
end

puts f(2, 3)
values = [3, 4]
puts values

puts f(values[0], values[1])

# puts f(values)
# Error: wrong number of arguments for 'f' (given 1, expected 2)
