Problem Solution:

In this program, we will create a hash collection then we will iterate elements of a hash collection using each() method and print the result.

Program/Source Code:

The source code to iterate elements of a hash collection using each() method is given below. The given program is compiled and executed on Windows 10 Operating System successfully.

# Ruby program to iterate elements of 
# hash collection using 
# each() method

hash = { "a" => 100, "b" => 200, "c" => 300,"d" => 400};

puts "Hash collection elements: ",hash.each{};

Output:

Hash collection elements: 
{"a"=>100, "b"=>200, "c"=>300, "d"=>400}

Explanation:

In the above program, we created a hash collection to store student information. Then we used each() method to iterate hash elements and printed the result.
