        More Info

        The type of an integer literal depends on three parameters: the value of the literal, whether it is written in decimal or not, and its suffix.

        A literal with a single L (or l) will usually be of a (possibly unsigned) long type. But if its value cannot be represented in this type, it will be of a (possibly unsigned) long long type instead.

        In such a case, it is more straightforward to use LL in the literal suffix, which unambiguously specifies a long long type.

        Note: This rule targets classical integer literals, not user-defined literals whose type is entirely determined by their suffix.
