<p>Bun. Deci o constructie <b>var x = expresie <operator> while ...</b> trece cu succes de analiza sintactica.</p>
<p><br>
</p>
<p>One more question, though (desi nu are legatura cu while sau if): Am observat, de asemenea, ca in manual operatorul
<b>!</b> are precedenta mai mica decat operatorul unar <b>- </b>toti ceilalti operatori binari<b></b>. Asta inseamna ca o expresie de genul !5 + 3 va fi evaluata la fel ca si expresia !(5 + 3) si nu (!5) + 3. Care e rezultatul dorit?</p>

<div>Dpdv sintactic constructia ar fi corecta.

<div class="">Salut,
<div class=""><br class="">
</div>
<div class="">Tipul unei expresii IF este dat de tipul ultimei instructiuni/expresii din cele doua ramuri. Prin urmare o expresie IF poate avea tipul Int. </div>
<div class="">Tipul unei expresii WHILE este mereu Void, in cazul in care ar aparea intr-o expresie de genul var x = 2 + while …, ar fi o eroare semantica, pentru ca tipul Void nu poate fi convertit la Int.</div>
