# declaring array
b = [1, 4, 1, 1, 88, 9]
# declaring array
c = [18, 22, 50, 6]
# to_a method example
puts "to_a() method form : #{a.to_a()}\n\n"
puts "to_a() method form : #{b.to_a()}\n\n"
puts "to_a() method form : #{c.to_a()}\n\n"
输出:
to_a() method form : [18, 22, 33, nil, 5, 6] to_a() method form : [1, 4, 1, 1, 88, 9] to_a() method form : [18, 22, 50, 6]
示例2:
# Ruby code for to_a() method
# declaring array
a = ["abc", "nil", "dog"]
# declaring array
c = ["cat", nil]
# declaring array
b = ["cow", nil, "dog"]
# to_a method example
puts "to_a() method form : #{a.to_a()}\n\n"
puts "to_a() method form : #{b.to_a()}\n\n"
puts "to_a() method form : #{c.to_a()}\n\n"
输出:
to_a() method form : ["abc", "nil", "dog"] to_a() method form : ["cow", nil, "dog"] to_a() method form : ["cat", nil]
