What is base of any C program?

The base of any C program is the main function, which serves as the entry point for execution. Every C program must include this function, which is defined with the signature int main() or int main(int argc, char *argv[]). Within main, the program's logic is implemented, and it typically returns an integer value indicating the success or failure of the program. Additionally, the program may include preprocessor directives, variable declarations, and function definitions that support its functionality.
