Re: [julia-users] Re: How to Manipulate each character in of a string using a for loop in Julia ?

[Erik Schnetter]

Alternatively, convert the string to an array of characters, which is
mutable:

```Julia
a = Vector{Char}("abcd")
for i in 1:length(a)
   a[i] += 1
end
```

I think Jacob meant:

for char in a
   write(io, char + 1)
end

Hello Jacob !!..
I get this error while trying to run your code:

Error evaluating cyclic.jl
