/**
 * First:

 * (fd) or a file descriptor is a number that uniquely identifies 
 * an open file in a computer's operating system. It describes a 
 * data resource, and how that resource may be accessed.
 * 
 * second:
 * =======
 * ft_putchar_fd():
 * Is the same as ft_puchar() function, BUT rather than writing to the 
 * standard output, we write the char (c) to a file descriptor 
 * obtained from the open system call.
 * 
 * This function gonna be used in ft_printf project.
