Answer / Atul Raj
In C, you usually don't need to define the standard library functions because they are already defined by the compiler. However, if you want to include them in your code for clarity or portability, some common header files include stdio.h (for input/output operations), stdlib.h (for general utility functions), string.h (for string manipulation functions), and math.h (for mathematical functions).
