Problem Solution:

In this program, we will create the object of the Set class. Then we will add the elements into the set using add() method of the Set class and print the set items using the "for" loop.

Program/Source Code:

The source code to get the items from a set using the "for" loop is given below. The given program is compiled and executed successfully.

# Ruby program to get the items from 
# a set using "for" loop

require 'set';

setObj = Set.new();

setObj.add(101);
setObj.add(102);
setObj.add(103);
setObj.add(104);
setObj.add(105);

puts "Set elements: ";
for item in setObj
   print item," ";
end

Output:

Set elements: 
101 102 103 104 105

Explanation:

In the above program, we imported the "set" package using the "require" statement. Then we created the object setObj of the Set class using the new() method and, we added 5 integer items into created set using add() method of the Set class. After that, we accessed the items from the set using the "for" loop and printed them.
