Xrnsimopoieis tis fgets(), strtok() kai strtol() kai ftuveis auto to aisxro
pragma pou legetai scanf().

% Px. exoume char line[80]; opou exei to periexomeno:
% 0 123 3441234 532525 4634636 575745 (pithana kai kana \n sto telos)
% kai exoume to long lt[6];

Xwris va to exw kavei compile, mia prwtn idea eivai:

	#include <stdio.h>	/* printf() in here */
	#include <stdlib.h>	/* strtol() in here */
	#include <string.h>	/* strtok() in here */
	#include <errno.h>	/* `errno' in here  */

	function koko (void)
	{
		char line[80];
		long lt[6];
		char *token;
		int k;

		strncpy(line, 79, "0 123 3441234 532525 4634636 575745");

		token = strtok(line, " \t\n");
		if (token == NULL)
			return EXIT_FAILURE;

		errno = 0;
		lt[0] = strtol(token, NULL, 10);
		if (errno == ERANGE)
			return EXIT_FAILURE;

		for (k = 1; k < 6; k++) {
			errno = 0;
			token = strtok(NULL, " \t\n");
			if (token == NULL)
				return EXIT_FAILURE;
			lt[k] = strtol(token, NULL, 10);
			if (errno == ERANGE)
				return EXIT_FAILURE;
		}

		for (k = 0; k < 6; k++)
			printf("[%d] %ld\n", k, lt[k]);
		fflush(stdout);
	}

Mou fainetai pos prepei na douleuei kala, gia dokimase to... kai tis
*scanf() functions apla ksexna tes, opws lene ki oi K&R sto biblio
"The C Programming Language" einai apla KAKES functions.
