Wow… I am amazed… but like… how do these loops work? (I mean, in the following example, char could be anything, right?)

Let’s say we have the code:

var funFact = "exlxephxxxaxnts xcaxxn'xxt xxxjxumxpx."
for char in funFact {
  if char != "x" {
    print(char)
  }
}

Another question I have is, how can we set char to not print multiple characters? For example, if I didn’t want to print “x” and didn’t want to print “e” ?

Thanks in advance! ^U^

I blindly followed the instructions this time since I was not looking to fully grasp as I was looking to get my daily coding in. Though to my surprise I passed each step whilst understanding it without giving it much thought. For instance how one practices something and through that repetition it pays off. So it was nice to see that I was grasping coding like this !!
