Technician comments can be modified for a pending Work Order??

The code will compile because in C, printf() will be implicitly declared if stdio.h is not included. The compiler will assume it returns int. This may generate a warning but will not prevent compilation. The code may fail at runtime on some systems if the implicit declaration doesn't match the actual signature, but compilation itself succeeds. Option C is incorrect because linking would fail if there were missing symbols, not just a missing header.
