# Ruby program to create a user define function 
# with arguments but without return value

def AddNum(num1, num2)
   add = num1 + num2;
   print "Addition is: ",add;
end

print "Enter number1: ";
num1 = gets.chomp.to_i;  

print "Enter number2: ";
num2 = gets.chomp.to_i;  

AddNum(num1, num2);

Output:

Enter number1: 10
Enter number2: 20
Addition is: 30

Explanation:

In the above program, we created a function AddNum() with two arguments. In the AddNum() function, we added the value of both specified arguments and printed the result. Here, we read two integer numbers and passed both numbers into AddNum() function for addition.
