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” ?
