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.

It returns a Boolean value. Here, we checked item 40, 35 items are included in the array arr or not and printed appropriate message.
