# Example markdown

Compare the processed version of this file with its unprocessed form.

## The includes

The includes are important to tell the compiler what to expect later. In the example file, the includes are :

```cpp
#include <iostream>
#include <factorial.h>
```

## The factorial function

The factorial function is implemented recursively. It is defined in another file called `factorial.cpp` :

```cpp
int factorial(int n) {
    if (n <= 1) {
        return 1;
    }
    return factorial(n-1) * n;
}
```

The corresponding header file is :

```cpp
#pragma once

int factorial(int n);
```

## Some other function

Some other function is implemented in the `example_code.cpp` file.
While the snippet is defined in the C++ file, we can decide to not use it in the documentation.

## Main function

In order to call all the functions defined above, the main function is implemented as such :

```cpp
int main() {
    // Call the factorial function
    std::cout << factorial(5) << std::endl;
    
    // Call some_function
    std::cout << some_function(3) << std::endl;
    return 0;
}
```
