What is a function in C

A function is a block of code that performs a specific task. Functions are used to break down complex problems into smaller, manageable parts, making the code more organized, reusable, and easier to understand. A function in C allows you to execute a particular piece of code multiple times without rewriting it.

Key Characteristics of Functions in C:

1. Reusability: You can call a function multiple times from different parts of your program.
2. Modularity: Functions help break a program into smaller, more manageable chunks, making it easier to debug, maintain, and understand.
3. Abstraction: You can use functions to hide complex logic, presenting a simple interface to the rest of the program.

Function Structure:

A function in C consists of the following parts:

1. Return Type: Specifies the type of value the function will return (e.g., int, float, void).
2. Function Name: The name used to identify and call the function.
3. Parameters (optional): A list of variables that the function will take as inputs (known as parameters or arguments).
4. Function Body: The block of code that defines what the function does. This is enclosed in curly braces {}.
