Problem Solution:

In this program, we will create two variables and initialize them with some values. Then we will find the created variables contain an ODD number or not using library function odd?().

Program/Source Code:

The source code to check the given number is an odd number using the library function is given below. The given program is compiled and executed successfully.

# Ruby program to check given number is an 
# odd number using library function

num1 = 20
num2 = 3

if num1.odd?()
    print "num1 is an odd number\n";
else
    print "num1 is an even number\n";
end

if num2.odd?()
    print "num2 is an odd number\n";
else
    print "num2 is an even number\n";
end

Output:

num1 is an even number
num2 is an odd number

Explanation:

In the above program, we created two variables num1, num2 and initialized 20, 3 respectively. Then we used the odd?() function to check created variables contains the odd number or not and printed the appropriate message. The odd?() function returns a Boolean value. It returns true when the variable contains an ODD number, otherwise, it returns false.
