红宝石 |使用 (+)函数的数组连接

Array#+()是一个 Array 类方法，它通过将两个数组组合到第三个数组来执行集合连接操作数组。

Syntax: Array.+()

Parameter: Arrays for performing the concatenation operation.

Return: New arrays by combining two arrays.

示例 #1：

# Ruby code for +() method
# showing concatenate operation
  
# declaring array
a = [18, 22, 33, 4, 5, 6]
  
# declaring array
b = [5, 4, 22, 1, 88, 9]
  
# declaring array
c = [18, 22, 33, 40, 50, 6]
  
# combining arrays
puts "combination of a and b : #{a + b}\n\n"
  
# combining arrays
puts "combination of a and c : #{a + c}\n\n"
  
# combining arrays
puts "combination of b and c : #{b + c}\n\n"

输出 ：

combination of a and b : [18, 22, 33, 4, 5, 6, 5, 4, 22, 1, 88, 9]

combination of a and c : [18, 22, 33, 4, 5, 6, 18, 22, 33, 40, 50, 6]

combination of b and c : [5, 4, 22, 1, 88, 9, 18, 22, 33, 40, 50, 6]

示例 #2：

# Ruby code for +() method
# showing concatenate operation
  
# declaring array
a = ["abc", "xyz", "dog"]
  
# declaring array
b = ["cow", "cat", "dog"]
  
# declaring array
c = ["cat", "1", "dog"]
  
# combining arrays
puts "combination of a and b : #{a + b}\n\n"
  
# combining arrays
puts "combination of a and c : #{a + c}\n\n"
  
# combining arrays
puts "combination of b and c : #{b + c}\n\n"

输出 ：

combination of a and b : ["abc", "xyz", "dog", "cow", "cat", "dog"]

combination of a and c : ["abc", "xyz", "dog", "cat", "1", "dog"]

combination of b and c : ["cow", "cat", "dog", "cat", "1", "dog"]
