Basic Structure of C Programming Quiz

The main() function is the entry point of a C program. It is where the program begins its execution. All C programs must have a main() function, and the program execution starts from the first statement within the main() function.

A C program consists of various components including header files, global declarations, function declarations, and the main function. The basic structure involves including header files, defining global declarations, declaring functions if necessary, and writing the main function where the program execution begins.

Header files in C programming contain function prototypes and declarations that are used in the program. They allow the program to access predefined functions and constants. One commonly used header file is 'stdio.h', which is used for input and output operations.
