Ruby program to create a user-defined function with arguments but without a return value

Last Updated : December 15, 2025

Problem Solution

In this program, we will create a user-defined function with two arguments. Here we will add both arguments and print the result.

Program/Source Code

The source code to create a user-defined function with arguments but without return value is given below. The given program is compiled and executed successfully.

# 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.
