Anatomy of a C Program

Standard structure includes:
- Program header and comments for clarity.
- int main(void) as the main function where execution begins.
- Statement terminates with a semicolon.
- printf() function for output, with return 0; indicating successful completion.

Comment and Preprocessor Directives

Comments help readers understand code and begin with /* and end with */.
Preprocessor directives (e.g., #include) include libraries, enabling access to predefined functions like printf() without rewriting complex code.
Essential for program readability and efficiency, allowing programmers to utilize existing functions and libraries.
