== Why is this an issue?

When ``++sizeof++`` is used on a pointer, it returns the size of the pointer (4 or 8 bytes, depending on architecture and OS), not the size of the pointed-to memory area. Therefore, division of that value is not likely to yield what was intended.


=== Noncompliant code example

[source,cpp]
----
char* message = "hello world";
sizeof(message) / 4; // Noncompliant
----
