Julia Language Hello, World!


Example

Strings in Julia are delimited using the " symbol:

julia> mystring = "Hello, World!"
"Hello, World!"

Note that unlike some other languages, the ' symbol cannot be used instead. ' defines a character literal; this is a Char data type and will only store a single Unicode scalar value:

julia> 'c'
'c'

julia> 'character'
ERROR: syntax: invalid character literal

One can extract the unicode scalar values from a string by iterating over it with a for loop:

julia> for c in "Hello, World!"
           println(c)
       end
