A function in C is a block of code that performs a specific task. Functions can take input in the form of parameters and can return a value or output. Functions can be called multiple times, which makes them reusable and modular.
There are four types of user-defined functions divided on the basis of arguments they accept and the value they return:
Function with no arguments and no return value.
Function with no arguments and a return value.
Function with arguments and no return value.
Function with arguments and with return value.

A structure is a collection of objects that are related logically. For example, you can create a structure to store employee information. Structures can be used to represent real-world objects, such as a point in 2D space, a customer record in a database, or a complex number. You can define functions inside a structure as member functions. These functions have access to the member variables of the structure and can be used to manipulate them.

The structure of a C program consists of the following sections:
Documentation.
Preprocessor directives / Header files.
Global variables.
Main function.
Other functions.

The main function is the starting point for program execution in C. It controls program execution by calling other functions in the program.
