file foo.h :: int id_O; // (captial letter O)
file bar.h :: int id_0; // (numeric letter zero)
|
If a file foobar.h includes both foo.h and bar. h and another file foobar.c that includes foobar.h uses both id0 and idO, it is a violation of DCL02-C.
...
In a compliant solution, use of visully similar identifiers should be avoided in the same project scope.file foo.h :: int id_a;
file bar.h :: int id_b;
