# ./write_on_stderr

A binary that writes on standard error the first given argument (the same behavior as `echo` but with only one argument) and exits with an error status code given as second argument. If no argument is given, it writes the string "write on stderr" and exit with status `1`.

```c
#include <unistd.h>
#include <string.h>
#include <stdlib.h>

int	main(int argc, char **argv)
{
	if (argc > 1)
	{
		write(2, argv[1], strlen(argv[1]));
		write(2, "\n", 1);
	}
	else
	{
		write(2, "write on stderr\n", 16);
	}
	if (argc == 3)
		return (atoi(argv[2]));
	return (1);
}
```
