In this program, we will create 2 variables and initialize them with some values. Then we will find the created variables contain an EVEN number or not using library function even?().
The source code to check the given number is an EVEN number using the library function is given below. The given program is compiled and executed successfully.
# Ruby program to check the given number is
# an EVEN number using library function
num1 = 20
num2 = 3
if num1.even?()
print "num1 is an EVEN number\n";
else
print "num1 is an ODD number\n";
end
if num2.even?()
print "num2 is an EVEN number\n";
else
print "num2 is an ODD 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 even?() function to check created variables contains the EVEN number or not and printed the appropriate message. The even?() function returns a Boolean value. It returns true when the variable contains an EVEN number, otherwise, it returns false.
