C Functions

C functions are blocks of code that perform specific tasks, encapsulated within a name, which can be invoked when needed. Functions allow code reuse, modular design, and improved readability. A typical C function consists of:
Return type: The type of value the function returns (e.g., int, void).
Function name: The identifier used to call the function.
Parameters: Optional input values provided to the function.
Body: The block of code executed when the function is called, enclosed in braces {}.
A simple example:
int add(int a, int b) {
return a + b;
}
Here, add is a function that takes two integers and returns their sum.
