What are functions in C language?
Understand the Problem
The question is asking for an explanation of what functions are in the C programming language, which involves understanding their definition, purpose, and how they are used within C programs.
Answer
A function in C is a set of statements that perform a specific task, enclosed within curly brackets, and allow for reusability and modularity.
A function in C is a set of statements enclosed within curly brackets ({}) that take inputs (known as parameters), perform a computation, and provide an output. Functions are the basic building blocks of a C program, allowing for code reusability and modularity.

More Information
In C programming, using functions improves code readability and efficiency. They allow programmers to break down complex problems into simpler, modular tasks.
Tips
A common mistake is not properly declaring functions before using them. Ensure that function declarations (prototypes) are included before the main function or within a header file to avoid compilation errors.
