Private function prototypes

Private function prototypes are function declarations that are only visible within the current source file and cannot be accessed from other source files or modules. They are typically used to declare helper functions that are used internally by the source file but are not part of the public API.
To declare a private function prototype, you can use the static keyword in front of the function declaration:
```c
static int helper_function(int arg1, int arg2);
```
This will make the function visible only within the current source file. Other source files that include the same header file will not be able to access this function.
Private function prototypes are useful for encapsulating implementation details and reducing namespace pollution. They also help enforce information hiding and modularity in large codebases.
