I am sharing with you, a simple program in Ruby to add two numbers:
Ruby
print “Enter the first number: “
FirstNo = gets.chomp.to_i
print “Enter the second number: “
SecondNo = gets.chomp.to_i
sum = FirstNo + SecondNo
puts “The sum of the two numbers is: #{sum}”
Step 1: user is will enter two numbers
Step 2: two numbers are stored in the variables and variables are FirstNo and SecondNo.
Step 3: The to_i method is used to convert the input to an integer because input is initially a string.
Step 4: the sum of the two numbers is calculated
Step 5: sum of the two numbers is stored in the variable sum.
Step 6: The puts method is used to print out the result.
