If the programmer decided to go a sort various in the listing of kind accepted ,there although be no error thrown at compile time.

Initial issues very first. C, i.e. ISO/IEC 9899 has experienced a boolean form for 19 many years now. That is certainly way for a longer time time than the predicted length of your C programming vocation with novice/educational/Experienced elements merged when visiting this concern.

typedef struct S int x; T; void S() // correct //void T() // mistake: image T now outlined being an alias to 'struct S'

My encounter continues to be No. But I assume It truly is usually accurate that checking an instance might have to occur at runtime, While checking a class ought to be doable at compile time.

As Some others have mentioned, You can not extract the sort of a variable at runtime. Nonetheless, you could possibly assemble your own "object" and shop the type in addition to it. Then you'll be able to Verify it at runtime:
