#3164

Se dau n, reprezentând numărul de elevi apoi, pe câte un rând, datele fiecărui elev: codul (număr natural de maxim 4 cifre), media la informatică (număr natural de la 1 la 10) și numărul de absențe. Definiți un tip structură pentru a putea memora datele unui elev și rezolvați cerințele:

a) memorați datele tuturor elevilor într-un vector de structuri de tipul definit;
b) afișați numărul de elevi cu media 10
c) afișați media clasei (se va afișa doar partea întreagă a ei).
d) afișați primii doi elevi după absențe (elevii cu cele mai multe absențe). Dacă sunt mai mulți elevi cu același număr de absențe se afișează în ordine crescătoare a codului. Dacă sunt mai mult de doi elevi număr maxim de absențe se afișează doar doi.

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:

  • probleme la care rezolvarea presupune scrierea unui program complet
  • probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.

Problema qclasa face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:

  • Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
  • Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.

Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.

Du-te sus!
