OK.
| int D(void) { return a['%']; } // Spurious C++ warning, no C warning
The absence of warning in C is OK -- literal characters have type int
in C. The warning in C++ is arguably bogus because the value of the
character '%' is known at compile-time, consequently the warning is
unwarranted (unless it really is negative).
