ruby - Using for-loop to add numbers together -


if randomly put in 2 numbers (first number smaller), how use for-loop add numbers between , itself?

ex: first number: 3

second number: 5

the computer should give answer of '12'.

how do using for-loop?

simple loop across range defined:

puts "enter first number: " first = gets.to_i puts "enter second number: " second = gets.to_i  total = 0 in (first..second)   total += end  puts total

note if don't enter valid number, converted 0. assumes second number larger first.
