Assignment name  : aff_a
Expected files   : aff_a.c
Allowed functions: write
--------------------------------------------------------------------------------

Write a program that takes a string, and displays the first 'a' character it
encounters in it, followed by a newline. If there are no 'a' characters in the
string, the program just writes a newline. If the number of parameters is not
1, the program displays 'a' followed by a newline.

Example:

$> ./aff_a "abc" | cat -e
a$
$> ./aff_a "RaInB0w d4Sh!" | cat -e
a$
$> ./aff_a "ThE Ck3 Is L|3" | cat -e
$
$> ./aff_a | cat -e
a$

#include <unistd.h>

void	aff_a(char *str)
{
	while (*str != '\0')
	{
		if (*str == 'a')
		{
			write(1, "a", 1);
			break;
		}
		++str;
	}
	write(1, "\n", 1);
}

int		main(int argc, char **argv)
{
	if (argc == 2)
		aff_a(argv[1]);
	else
		write(1, "a\n", 2);

	return (0);
}
