Duh!! Compilation error

It's I

Missing #include ....

Answer 2

Option a:compilation error:

Explanation:

• The above code is in c language, which has not the complete syntax which adds the header file.
• So the compile-time error occurs on the place of "#include". It can be written as "#include<stdio.h>".
• If the user fixes the above error, then the above program runs the infinite loop. Because the character data type range varies from -128 to 127.
