# Entry point to C programs

```c
int main(void)
{
    // Instructions
}
```

The braces wrap all code that comprises the program.

The return type is `int`. It receives no arguments so the arguments are `void`.

## Why does it return an `int`?

It returns an `int` because the main function returns a success code: `0` for
success and `1` for error.

As C was divised to create Unix, this fits in with other Unix-like OS behaviour
such as bash scripts returning `0`/`1`.
