Question

Answer 1

in preprocessing step, using #define we can't replace int which is a predefined data type so error

Comments

preprocessor does not know of the datatypes rt?

---

Yes The preprocessor does not know anything about types in the language.

I think here option D should be correct.

arr1 list={0,1,2,3};

But arr1 is not declared inside main.So compilation error.

---

yes.

#define <identifier> <replacement-token>

int is not an identifier

@why to declare arr1

here list is declared which is of type arr1 and arr1 is int as per #define directive so before compilation preprocessing takes place where pre-processor can't recognise int as an indentifier

because int is a keyword in C...I think is is violation of preprocessing directive syntax rule so compilation error..ryt?
