__ STDC__ 当编译器以 ANSI 标准编译时,则定义为 1。 让我们来尝试下面的实例: #include main() { printf("File :%s\n", __FILE__ ); printf("Date :%s\n", __DATE__ ); printf("Time :%s\n", __TIME__ ); printf("Line :%d\n", __LINE__ ); printf("ANSI :%d\n", __STDC_...

C Language Changes in Clang • The value of __STDC_VERSION__ has been bumped to 202000L when passing -std=c2x so that it can be distinguished from C17 mode. This value is expected to change again when C23 is published. • Wide multi-characters literals such as L'ab' that would ...
