Last Updated : December 15, 2025

Problem Solution

In this program, we will read two integer numbers from the user and multiply both numbers using the plus (+) in "while" loop and print the result.

Program/Source Code

The source code to multiply two numbers using the plus (+) operator is given below. The given program is compiled and executed successfully.

# Ruby program to multiply two numbers 
# using the plus (+) operator

cnt=0
mul=0
num1=0
num2=0

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

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

while(cnt<num2)
    mul += num1;
    cnt = cnt+1;
end
        
print "Multiplication is: ",mul;

Output

Enter number1: 4
Enter number2: 6
Multiplication is: 24

Explanation

In the above program, we created four variables num1, num2, cnt, mul initialized with 0. Then we read values num1 and num2 from the user. After that, we multiplied both numbers using the plus (+) operator in the while loop and printed the result.
