Ruby Question
An integer I pass as an argument becomes a method
I am trying to write a function. Here is the code.
def get_sum(a,b)
if a == b do
return a
end
else
total = 0
for num in a...b
total += num
end
return total
end
end
I get this error:
undefined method `b' for main:Object (NoMethodError)
Can anyone tell me why I get this?

No do for ifs
if a == b
return a
end
Note that you can do the same thing so
def get_sum(a, b)
return a if a == b
(a...b).inject(:+)
end
