However, in the following expression: <pre> (x==6 || x==5) </pre> the || represents an "or" meaning if x is equal to 6 OR x is equal to 5. And it is equal to 5. so the entire expression is true. In the case of an AND: <pre> (x==6 && x==5) </pre> since x cannot be both 6 and 5 at the same time, that expression is clearly false. x does not equal 6, x equals five. However, in the following expression:

(x==6 || x==5)

the || represents an “or” meaning if x is equal to 6 OR x is equal to 5. And it is equal to 5. so the entire expression is true.

In the case of an AND:

(x==6 && x==5)

since x cannot be both 6 and 5 at the same time, that expression is clearly false.

I got the others right. Is this meaning that in some cases 5 == 6? Wait, so how can x==6 || x==5 be true if x=5? I got the others right. Is this meaning that in some cases 5 == 6?
