| Comparison operators are the usual mathematical operators you're familiar with. The result of their application is a ''bool'' (e.g. a < b is either ''true'' of ''false''). This is why they can be used in if-statement and loop conditions. This also means that their result can be assigned to ''bool'' variables, like this:\\ | Comparison operators are the usual mathematical operators you're familiar with.
