Ruby | Array Concatenation using (+) function

Last Updated : 07 Jan, 2020

Array#+() is a Array class method which performs set concatenate operation arrays by combining two arrays to a third array.

Syntax: Array.+() Parameter: Arrays for performing the concatenation operation. Return: New arrays by combining two arrays.

Example #1 :

Ruby

# 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"

Output :

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]

Example #2 :

Ruby

# 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"

Output :

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"]
