Introduction to Function

A function in C is a block of code that performs a specific task. It allows programmers to divide a large program into smaller, manageable, and reusable sections.

• Functions take input, process it, and return output (though not always).
• They help improve code modularity, reusability, and readability.

Syntax of a Function:

return_type function_name(parameter_list) {
    // Function body
}

Benefits of Using Functions:

• Avoids code repetition
• Makes debugging and testing easier
• Promotes code reuse
• Improves structure and readability
