Se verifică dacă numărul este 2, în caz contrar se începe căutarea divizorilor de la 3. Dacă numărul este divizibil cu un număr impar sau cu 2, se trece la următorul număr. În caz contrar, se continuă căutarea divizorilor până la radicalul numărului. Dacă numărul este prim, se adaugă 1 la variabila &#039;&#039;&#039;C&#039;&#039;&#039;. La final se scrie rezultatul în fișierul &#039;&#039;&#039;eratostene.out&#039;&#039;&#039;.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

== Cerinţa ==&lt;br /&gt;
Se dau &amp;#039;&amp;#039;&amp;#039;n&amp;#039;&amp;#039;&amp;#039; numere naturale mai mici decât &amp;#039;&amp;#039;&amp;#039;1.000.000&amp;#039;&amp;#039;&amp;#039;. Determinaţi câte dintre ele sunt prime.&lt;br /&gt;
== Date de intrare ==&lt;br /&gt;
Fişierul de intrare &amp;#039;&amp;#039;&amp;#039;eratostene.in&amp;#039;&amp;#039;&amp;#039; conţine pe prima linie numărul &amp;#039;&amp;#039;&amp;#039;n&amp;#039;&amp;#039;&amp;#039;; urmează cele &amp;#039;&amp;#039;&amp;#039;n&amp;#039;&amp;#039;&amp;#039; numere, dispuse pe mai multe linii şi separate prin spaţii.&lt;br /&gt;
== Date de ieșire == &lt;br /&gt;
Dacă datele sunt introduse corect, pe ecran se va afișa: &lt;br /&gt;
&amp;quot;Datele sunt corecte.&amp;quot;, iar apoi in fişierul de ieşire &amp;#039;&amp;#039;&amp;#039;eratostene.out&amp;#039;&amp;#039;&amp;#039; va conţine pe prima linie numărul &amp;#039;&amp;#039;&amp;#039;C&amp;#039;&amp;#039;&amp;#039;, reprezentând numărul valorilor citite care erau numere prime. În caz contrar, se va afișa pe ecran: &amp;quot;Datele nu sunt comform restricțiilor impuse.&amp;quot;.&lt;br /&gt;
