Problem Solution:

In this program, we will create an array of integers then we will check given item is included in the array or not.

Program/Source Code:

The source code to check given item is included in the array or not is given below. The given program is compiled and executed successfully.

# Ruby program to check given item is 
# included in the array or not

arr = [10,20,30,40,50];

if arr.include?(40)
    print "Item 40 is included in the array.\n";
else
    print "Item 40 is not included in the array.\n";
end     

if arr.include?(35)
    print "Item 35 is included in the array.\n";
else
    print "Item 35 is not included in the array.\n";
end

Output:

Item 40 is included in the array.
Item 35 is not included in the array.

Explanation:

In the above program, we created an array arr with some elements. Then we used the select() method. The include?() method is used to check given item is included in the array or not. It returns a Boolean value. Here, we checked item 40, 35 items are included in the array arr or not and printed appropriate message.
