numeros = [1, 2]
class C
def calcule_array(*numeros)
puts a + b
end
end
numeros = C.new
puts numeros
I would like to know how I can do calculations with integers that are inside an array in Ruby, I tried the above code but without success.
Important points:
splat operator that is before the parameter name *numeros
numeros when you instantiate the class C
Then you can use the inject or < a href="http://ruby-doc.org/core-2.5.3/Enumerable.html#method-i-reduce"> reduce
numeros = [1, 2, 3, 4]
class C
def calcule_array(numeros)
puts numeros.reduce(:+)
end
end
calcular = C.new
calcular.calcule_array(numeros)
Output:
> 10
