General Structure of C Program

The structure of a C program can be divided into several sections:

Document section: This section consists of comments and documentation that describe the purpose and usage of the program. These comments are ignored by the compiler and are intended for human readers.
Link Section: This section includes #include directives, which tell the compiler to include the contents of other files in the program. These files may contain function declarations, data definitions, or other information that is needed by the program.
Global Section: This section includes declarations of variables and functions that are accessible from any part of the program. These variables and functions are called global because they are not bound to a specific function and can be accessed from any function in the program.
Main Section: This section contains the main function, which is the entry point of the program. The main function is where execution begins when the program is run, and it typically calls other functions to perform specific tasks.
Subprogram Section: This section contains additional functions that are called by the main function or by other functions. These functions may perform specific tasks or may be used to break up a larger problem into smaller, more manageable pieces.

Overall, the structure of a C program is designed to make it easy to write, debug, and maintain large programs by dividing them into smaller, modular units.
