An integer array will not be able to store characters in it. * Arrays have separate positions that can be declared with brackets, and accessed with square brackets. * Strings are arrays too, but we can treat them a little differently: they can be declared using double quotes, and printed using %s. * Strings have their own library, `string.h`, which has some handy functions to use.
