Answer 2

Answer:

The first line is executed by the Preprocessor.

(A) #include<stdio.h>

Explanation:

• The preprocessor executes the statements that start with the hash symbol(#).
• Generally, we use the # symbol for including header files and Marcos.
• Header files contain the functions that are already defined in the language itself while the macros contain the user-defined functions or constants.
• They are always used at the beginning of the program.
• Following is a list of preprocessor directives.

1. #include
2. #define
3. #undef
4. #ifdef
5. #ifndef
6. #if
7. #else
8. #elif
9. #endif
10. #error
11. #pragma
